To be fair, for guys the main attractions are (depending on the relationship dynamics) the trust involved or the feeling of dominance, and the taboo of the act. As far as physical sensations, I prefer vaginal sex overall. While anal feels “tighter,” at least at first, you also don’t get as much pressure on the frenulum and you don’t get as much of the grip and ripple effect that you can get from a woman who either has good muscular control, or who is just plain out of control from orgasming.
Oh yes, some women do indeed enjoy anal sex. One of my ex-girlfriends, after I introduced her to it, would occasionally request it. She often got very wild during and after those sessions. Subjectively, I think she got wetter than usual too. She told me that it was partly the idea of doing something “nasty” like that that turned her on so much, but the sensation was pretty fantastic too.
A different girlfriend liked it as part of a bondage scene. Tie her up and blindfold her and suddenly she’s asking to be #^¢*ed in the @$$ (her words). Surprised the hell out of me. All I thought I was going to do was the bondage stuff and suddenly she’s using explicit language and asking for something I normally have to slowly work up to. Surprised her too, from what she told me later. She hadn’t tried bondage before and anal suddenly seemed like it would be fun too. Serendipity at its best. Any guys who are reading this, don’t assume you’ll get this reaction when you tie a girl up. That was, literally, a once-in-a-lifetime thing for me. Oddly, she only really liked it as part of bondage. We tried it later without the ropes and she didn’t get anywhere near as much fun out of it, though she didn’t really dislike it either.
Other exs; some liked it, some didn’t. One girl, quite understandably, didn’t even want to try it due to having Crohn’s Syndrome. Back in my wilder youth, I pretty much tried everything sexual that didn’t conflict with one of my Four Rules, and I used to try and find things my girlfriends hadn’t done so that I could, you know, be the first at something. Yeah, I admit, it was flag-planting, but I always tried to make it mutually fun flag-planting.
Quite a few of them hadn’t tried it before me, some had been put off by ex-boyfriends trying it. Apparently, there are quite a few clueless guys who do the, “Whoops, I slipped and put it in the wrong hole,” thing. Needless to say, they got no more that night, and in a few cases were permanently banished. I think if someone unexpectedly jabbed a dick in my ass, I’d be pretty pissed off and he wouldn’t be getting any more fun-time from me either. Straight or gay, male or female, no one would think that’s nice.
