Most women who've been dating or in a relationship lately can attest to the male fascination with anal sex. While the no-no factor has always been part of the act's allure, the popularization of porn has made back-door booty increasingly mainstream.

While plenty of guys are curious about what brown can do for them, there's a huge range of ways they actually bring it up. From the guy who "casually" asks mid-sex to the one who negotiates with his wife for months over how, when and in exchange for what it'll take place, men's initiation tactics can be truly entertaining.

The Giggling Schoolgirl
"One guy I dated for a few months kept making fun of it," says Katie from Boston. "But he would keep bringing it up. It's like he was trying to use some weird reverse psychology on me or something. Finally I just had to come out and say, 'Let's just do it already so we can stop talking about it!'"

Did it work? Yep. Katie falls into the "I'll do it, but I don't love it" category, a sentiment we heard from a lot of our friends who've given anal a go. "It usually requires lots of alcohol and a fair amount of begging," she says.

The "Whoops!"
"I was in a long-term relationship with my college boyfriend who was pretty perfect for me in every way, except in the bedroom. He kept asking for anal and I kept telling him no. One day we were doing it, and he 'accidentally' put it in the wrong hole.' That was the end for me."

Did it work? "Let's just say I am more like Carol Brady on the sexual-adventuress scale, and I realized he was looking for Jenna Jameson," admits Amy of Chicago. Though to be fair, having someone try to sneak in through the exit door with no warning (or lube!!) is a turn-off regardless of whether you're into it under normal circumstances.

The Gamble
"I had a guy make a bet with me once. I lost, so he got anal," says Debi of San Francisco.

Did it work? "I never though I would love it as much as I do," she writes adding a "yes" emoticon. "My friends make fun of me and say I am the one girl that makes it hard for the rest of them -- the girl that gives guys the encouragement to continue on with the bum brigade."

We'd also bet that Debi's unique gambling ways have increased her invitations to poker nights.
