Probably a lot of the psychological appeal for women who like anal comes from it being taboo. But as far as physical pleasure goes, I can tell you there are WAY more nerve endings around the anus than in the vagina. I've not done anal with another person, but I've done some solo play. It just really intensifies orgasms. The usual focus of masturbation for me is the clit. I mean, that's really where all the nerve endings are, and unless I've had a couple of orgasms already I can't have a g-spot orgasm. But even if you add vaginal stimulation, it doesn't really intensify the orgasm because there just aren't that many nerve endings. Anal stimulation, however, makes my clitoral orgasms like...10 times more intense.
There are some reasons I have not asked for it in the context of a relationship, which may give you some ideas about why you've never been asked, Objective-J. The first is that when I do it, it is in the shower, on my own, when I know exactly what is going on with my body. With someone else, I'm trusting them not to freak out about...well the fact that it's a butt. The other reason is that the guy I was with was very clear that he was not into it at all. I will not ask for something, or even propose something, if a guy has already expressed an even remotely negative opinion about it. And here's the big reason. Good foreplay and a partner who is willing to stimulate other erogenous zones on my body to complete distraction (neck, stomach, etc...not just nipples for crying out loud), is JUST as effective at intensifying my orgasms as the stimulation from anal play, and in a lot of ways the foreplay is more intimate and comfortable. So, why even go for anal, when I get get the same incredible orgasm without having to worry about cleanliness, negative attitudes about it, feeling shameful about wanting it, etc.? It's like...I can highlight an important passage in yellow, or in orange. Either highlighter will accomplish the same damn thing, so it doesn't matter which I choose. So I'll go with "bite my neck and pull my hair" over "how do you feel about anal?" any day of the week.
