1. If you gain weight, some of it will go to your boobs.
2. After 50 it isn't just your ears and nose that get bigger, so do some of your lady bits.
Last month five mariachi singers rushed to the table where my husband Henry and I dined. They tripped, fell and were never seen again.
I think they fell into my vagina.
I can't be entirely sure because I didn't feel a thing. But sometimes in the shower I hear the faint echo of "Quan tan ameda o sea Quan tan ameda."
3. In your 50s you'll take orgasms any way you can get them.
Let's face it, people get very competitive about their orgasms, as if they were climbing Mount Everest.
Did you summit? Or did you only make it to base camp? Did you need an oxygen tank? Grappling hooks? A sherpa? Or were you able to summit barefoot reading Holy Sanskrits in Nirvanic Bliss?
My orgasms have always been like calculus. I have to stand on the big toe of my left foot, hips cantilevered toward Mecca, while singing peyote-inspired incantations over a burning sage bush as doves are released north-by-northwest into the Aurora Borealis.
These days I just don't care about orgasms. If they happen great, if they don't happen great. I GOT NOTHING LEFT TO PROVE, people!
4. After 50, sex is no longer as risky and may, in fact, keep us alive longer.
Unless we're Susan Sarandon or on a hormone cocktail, it's unlikely we'll become teen mothers. And we're more likely to die from heart arrhythmia than STDs.
At our age, sex pencils out cost-effective. It alleviates stress, boosts immunities and even lowers the risk of cancer.
And for those of us who are religious and having sex out of wedlock we don't care if we're going to burn in the everlasting fires of Hell, we just thank God we're getting laid.
5. In your 50s, you should occasionally try something new to spice things up.
Like maybe having sex in the back of your minivan on Beverly Drive at 11 p.m. on a Thursday night.
Not that my husband and I did that. But if, hypothetically, we did do that, the police officer that shined his flashlight into the cargo hold would find two middle-aged people so flattered to be booked on lewd and lascivious behavior that he wouldn't even bother.
It's no fun busting people who need hair plugs and bite guards.
6. At our age, there's no need to feel threatened by fantasies.
If you're having sex in your 50s it might be with someone you've known a long time. Someone who loves you even though he's seen you nurse your newborn on a toilet while trying to delicately deliver your first post-partum poop.
And it may be someone you love even though he's always leaving his poop in the toilet because he's so proud of it.
So if, from time-to-time, in your mind, you're making love to Chris Hemsworth fully equipped with Thor's Hammer or your partner tells you that Sofia Vergara just broke up with her boyfriend as he one-hands your bra clasp open, neither of you takes it personally.
7. After 50, sex is funny.
When I was younger, sex was serious business. It was very Melrose Place with intense gazes and catatonic Andrew Shue repartee. "Sydney, I want you. Oh, how I want you. But I'm troubled by my own beauty."
God forbid you make a sexual faux pas. Hairy armpits, big, grey underwear, some ill-timed vaginal flatulence.
Last month, when my husband rolled me powerfully beneath him, we both fell off the bed. I'll walk the rest of my life with a limp, but after we finished laughing we made love on the floor.
8. Finally, in your 50s it's a good idea to go to bed naked if you wanna get lucky.
Now you've got arthritis, carpel tunnel syndrome, cauliflower ear and phlebitis. You can't possibly expect to be able to shuck pajamas from a horizontal position.
And let's not forget the magnitude of entropy in our lives. My husband and I have been together seventeen years.
We have two daughters we have to keep off the stripper pole. Two cats who might eat us should we nap too soundly. And a 10-year old mini-van that smells like Jimmy Hoffa's corpse.
When we get into bed at night what we want to do is sleep. And if we're not sleeping we want to watch hot people having sex on Outlander or TMZ celebrity cellulite.
So when the Marriage Maintenance egg timer goes off we get into bed without the expectation of sex, but with the mandate of a massage.
Then things evolve. This man who piqued my curiosity and passion seventeen years ago has his hands on my body.
And this body that has had children and various age-related ailments suddenly takes on dimension.
His hands follow the curves as he massages and suddenly I have hips and thighs and belly and breasts that are soft in places, and still firm in places and wholly human and corporeal for my brief time here on planet earth.
And for that time, regardless of my age or in-and-out-of-shapeness, I re-inhabit my body. I'm reminded that I exist. And This. Is. Sexy.
