For me the idea of it, watching it, experiencing the girl's reaction to taking it up the bum, and knowing I'm doing it is all much more significant than the sensation. On sensation alone I prefer to fuck a nice wet pussy hard. If you've never done anal then I'd totally try it out though, but with someone who enjoys it and doesn't charge extra (unless they'll refund the extra if you can't get it in like Hayley). find a specialist, a total slut, an older wg or one who likes being fisted.
