Lena Dunham, director, writer and creator of HBO's hit series "Girls," knows a thing or two about women. In her latest ad for President Barack Obama, Dunham speaks to young female voters about making their "first time" count.

Some conservatives, however, are offended by the double entendre.

Dunham's Obama ad, appropriately titled "Lena Dunham: Your First Time," debuted on the official BarackObamadotcom YouTube channel on Thursday. In the ad, the "Girls" actress talks about her first time.

"Your first time shouldn't be with just anybody, you wanna do it with a great guy," says Dunham. "It should be with a guy with beautiful... Someone who really cares about and understands woman." Later joking, "It's also super uncool to be out and about and someone says, 'Did you vote?' and you say, 'No, I wasn't ready.'"

Alas, she is not talking about sex, but voting. "My first time voting was amazing," she says. "It was this line in the sand. Before I was a girl, now I was a woman."

Dunham tweeted to her followers, "My first time was with @BarackObama – I highly recommend you do the same."

The video may be light but the message is serious: vote for women's rights.

However, Dunham's ad did not resonate with conservatives, who deemed the "first time" pun inappropriate for a presidential election.

"How could a president with two, young blossoming daughters release an ad as disgusting as this," tweeted John Notle, Editor-at-Large at Breitbart News. Conservative commentator Joshua Trevino highlighted the comparison of Dunham's Obama ad to a Vladimir Putin ad from earlier this year: "So the Obama ad with Lena Dunham is a concept recycled from .... VLADIMIR PUTIN."

Dunham, whose HBO show has been called the "voice of a generation," is also being criticized for claiming Obama was her "first time."

Slate magazine, whose staff are "unabashed fans" of the "ascendent auteur" and her "adorable" campaign ad, noted that Dunham was born on May 13, 1986, making her 18 years old in 2004. That means she was of legal voting age when John Kerry faced George W. Bush in the election that year. But, Slate adds, "To be fair, I’d rather lose my voting virginity to Barack Obama than John Kerry, too."

Dunham's "first time" Obama ad did get some applause. Entertainment Weekly's Adam B. Vary described it as "a wryly hip ad that will likely appeal to Dunham’s fans (whose enthusiasm for the democratic process may have waned since the gonzo excitement of the 2008 election)." GQ's Reid Cherlin compared her to Donald Trump: "If it is possible for there to be such a thing as the opposite of Donald Trump's square, awkward 'deal' video, it's the web ad that Lena Dunham just cut for the Obama campaign."

The 26-year-old, who recently signed a book deal for more than $3.5 million, has been a public Obama supporter. She tweeted her endorsement earlier this month and recently filmed a rendition of "You Don't Own Me" with some noteworthy ladies like Lesley Gore and Tavi Gevinson.

  • Gwen Stefani

    The No Doubt singer and L.A.M.B. designer <a href="http://www.huffingtonpost.com/2012/03/12/obama-hollywood-democrats-super-pacs_n_1340385.html" target="_hplink">hosted the First Lady at her Los Angeles home in August</a>. That event was attended by Nicole Ritchie, Joel Madden, Jeffrey Tambor, Alyson Hannigan and No Doubt member Tony Kanal. Tickets were $2,500 for a family of four, and about 400 people were said to attend.

  • George Clooney

    The charming actor is undoubtedly the campaign's brightest star. Aside from hosting a dinner which <a href="http://www.huffingtonpost.com/2012/05/11/george-clooney-obama_n_1508850.html" target="_hplink">ended up bringing $15 million into the campaign's coffers</a> (through the sale of $40,000 tickets and a contest through which fans could enter to attend by donating $3), he has <a href="http://www.huffingtonpost.com/2012/03/12/obama-hollywood-democrats-super-pacs_n_1340385.html" target="_hplink">dialed up over $500,000 in Geneva</a> as well. The latter fundraiser featured contributors shelling out $15,000 each for dinner and another $5,000 for a photo with Clooney. The President has said the actor is a true and brilliant friend. He forgot to mention "highly lucrative."

  • Ben Affleck & Matt Damon

    ... and John Krasinski, Jennifer Garner, Reese Witherspoon, Zach Braff and Tobey Maguire. Though that list of names reads more like a red carpet tip sheet than a fundraiser guest list, all of the above celebrities <a href="http://www.huffingtonpost.com/2012/05/22/ben-affleck-elizabeth-warren-fundraiser_n_1537308.html" target="_hplink">lined up and brought out their check books for Elizabeth Warren</a>. The consumer advocate, law professor and creator of the Consumer Financial Protection Bureau got a big boost from the stars, who supported her bid to reclaim Ted Kennedy's Senate seat for the Democrats, from Scott Brown and the Republicans. A May event at "Lost" creator J.J. Abram's house was said to net over $250,000 for Warren's campaign. Harvey Weinstein, Jeffrey Katzenberg and Steven Spielberg were said to have sent checks.

  • Clint Eastwood

    Clint Eastwood It's a bit lonelier on the other side, but Clint Eastwood <a href="http://www.huffingtonpost.com/2012/08/03/clint-eastwood-romney-endorses_n_1740021.html" target="_hplink">made Romney proud</a> by endorsing the former governor's fiscal policy -- and handsome mug. At a fundraiser in early August, Eastwood announced he would vote for Romney, the type of candidate the actor said America needed "now more than ever." (Romney's reaction: "What a guy.") That puts Eastwood in the company of Kid Rock, Jon Voight and Kelsey Grammer.

  • Ryan Murphy

    The "Glee" creator was <a href="http://www.huffingtonpost.com/2012/05/11/ryan-murphy-barack-obama-fundraiser_n_1510006.html" target="_hplink">one of many Hollywood figures who brought out their checkbooks</a> in the wake of Obama's support of same-sex marriage. Julia Roberts, Jane Lynch and Reese Witherspoon were among those who took part in a fundraiser hosted at Murphy's home. About 70 people were said to attend, with tickets going for $40,000 per couple. If we assume most came as couples, a cool $1.4 million or more could have been raised.

  • Anne Hathaway

    The "Dark Knight Rises" actress has been spotted at Occupy Wall St. protests, so it's not shocking that she would lean a little to the left. She attended a fundraiser at Harvey Weinstein's house, <a href="http://www.huffingtonpost.com/2012/08/06/obama-anne-hathaway-aaron-sorkin_n_1749753.html" target="_hplink">where the president described her as "the best part" of the Batman movie</a>. ("Newsroom" and "West Wing" scribe Aaron Sorkin also got a plug: "He writes the way every Democrat in Washington wished they spoke.") The dinner, which cost $35,000 per person, was attended by Anna Wintour and Jerry Springer as well.

  • Mariah Carey

    The singer is currently working on a bit of a comeback, but a June fundraiser featuring a performance by Carey was <a href="http://www.huffingtonpost.com/2012/06/14/obama-sarah-jessica-parker-mariah-carey-fundraisers_n_1596020.html " target="_hplink">solid enough to bank $2.5 million for the president</a>. Mr. and Mrs. Obama were in attendance, and the event took place the same day as Jessica Parker's. Efficiency is always the aim, it seems.

  • Barry Meyer

    Warner Bros.' CEO (pictured here with Sen. Patrick Leahy and Clint Eastwood) presided over an event at his home, <a href="http://www.huffingtonpost.com/2012/08/13/gwen-stefani-michelle-obama-fundraiser-not-spiderman_n_1772046.html" target="_hplink">welcoming the FLOTUS into an eager crowd</a> that included WB TV President Peter Roth, Netflix executive Ted Srandos, HBO Vice-President James Costos, DreamWorks Animations COO Anne Globe. Chelsea Handler also attended. Tickets were $2,500 and a photo with Michelle Obama cost an additional $2,500.

  • Harvey Weinstein

    Back in May, Weinstein's overall contribution to Super PACs pointing Obama's way <a href="http://www.huffingtonpost.com/2012/03/12/obama-hollywood-democrats-super-pacs_n_1340385.html" target="_hplink">was already valued at nearly $700,000</a>. Since then, he's hosted a fundraiser at his home and referenced the president favorably in countless interviews. In Hollywood, it's good to have Hollywood on your side. Perhaps the same goes for Washington?

  • Sarah Jessica Parker

    The "Sex and the City" star <a href="http://www.huffingtonpost.com/2012/06/19/sarah-jessica-parker-obama-fundraiser_n_1609383.html" target="_hplink">hosted the president and first lady </a>at the home she shares with husband Matthew Broderick. There were about 50 who attended the highly exclusive event, and guests like Anna Wintour, Meryl Streep, Michael Kors and Aretha Franklin eagerly doled out the $40,000 ticket fee for the chance to mingle with the Commander in Chief. The dinner was said to have raked in $2 million for the campaign.

  • Spike Lee

    The "Red Hook Summer" director hosted the POTUS, who received not only $1.6 million (according to Lee), but <a href="http://www.huffingtonpost.com/2012/01/20/spike-lee-hosts-president-obama-fundraiser_n_1218479.html" target="_hplink">also a pair of custom Nikes</a>. Mariah Carey and Nick Cannon were among those who attended. Lee continues to speak favorably of Obama in interviews.

  • Lady Gaga

    Gaga may be busy touring and recording (naked), but the "Born This Way" pop star <a href="http://www.huffingtonpost.com/2011/09/26/lady-gaga-attends-obama-fundraiser_n_980505.html" target="_hplink">found time for a fundraiser in Silicon Valley</a>. As always, the singer dressed eccentrically, wearing a floor-length lace dress which she paired with a giant hair-do and a veil hair piece. Gaga had said she wanted to meet with Obama to discuss bullying.

  • The Cast & Creator of 'The Wire'

    Obama has shouted out David Simon's "The Wire" as his favorite show, so it's no wonder the cast of the program returned the favor in August. Multiple former cast members <a href="http://www.huffingtonpost.com/2012/08/17/the-wire-obama-fundraiser_n_1799304.html?utm_hp_ref=political-hollywood " target="_hplink">spoke at an event in Martha's Vineyard</a>, just a day after Simon ripped into Mitt Romney on his blog. Simon rejected Romney's attempt to calm a growing controversy surrounding his tax returns by assuring reporters that he had never paid below 13 percent, a number Simon found "absurd."

  • Kelsey Grammer

    The Frasier star <a href="http://www.huffingtonpost.com/2012/08/15/kelsey-grammer-emmys-snub-republican_n_1784677.html" target="_hplink">floated the idea that he was snubbed for an Emmy for "Boss" on account of his openly conservative views</a>. Grammer <a href="http://fundrace.huffingtonpost.com/neighbors.php?type=name&lname=grammer&fname=kelsey&search=Search+by+Name " target="_hplink">donated</a> to John McCain, Rudy Giuliani and George W. Bush when they were each running for office and has been all the more vocal about his views this time around.

  • Jon Voight

    What can be said? Angelina Jolie's father has made a cottage industry out of supporting Republicans, though he's a bit prone to gaffes. In a speech at the Republican National Convention, <a href="http://www.huffingtonpost.com/2012/08/28/jon-voight-obama-administration-media-control_n_1837409.html" target="_hplink">Voight compared Obama's administration to Cesar Chavez</a>, mistakenly invoking the co-founder of the National Farmworkers Association. It's safe to assume Voight meant to compare Obama to Venezuelan president Hugo Chavez. Voight has donated to conservative politicians in the past.

  • Bill Maher

    The comedian and talk show host <a href="http://www.huffingtonpost.com/2012/02/24/bill-maher-super-pac-obama-_n_1299250.html" target="_hplink">donated $1 million to Priorities USA,</a> a Super PAC which supports Obama and has also fielded contributions from Steven Spielberg. In an appearance on HuffPost Live, Maher explained that he hoped his decision would inspire others in Hollywood to do the same, and said he believed Morgan Freeman's recent donation proves that his plan had worked. He also frequently fact checks and disparages Romney and the Conservatives on his HBO show.
