So you're a single midlife woman and you care about sex? Then say so in your online dating profile. And no, I'm not just talking about women who are looking for casual fun, although that's a perfectly acceptable choice. I'm talking about any sexually charged woman who believes that good sex is a vital component of a romantic relationship and doesn't want to settle for anything less.
If you met an attractive man at a party, you would be showing him your best side and flirting up a storm. Your online dating profile is no different. It's the first introduction a man has to you. You are literally marketing yourself to the male population online. For some women that sounds horrid but in real life we do it all the time.
Online dating wouldn't be so bad if people just spoke to each other like humans. If I was at a bookstore and a guy wanted to approach me to say hello or get my attention, if he said something like, "Sup Cutie. You fine," and followed it up with a wink face, I'd be confused, embarrassed, and ultimately walk away.
