Because the treat in having anal sex with a girl is not in dipping the dick in shit. Erroneously so, you seem to have assumed that guys who like anal sex do it because it involves poo. How silly of you. It is in a) putting your penis into the forbidden hole, and b) the forbidden hole just happens to be tighter than the bidden hole, at least when you just get started with it.
You get to fuck the same girl, but in a tighter hole that you know "you're not supposed to be fucking". How is that not a win-win? And how in the hell would fucking another man achieve the same? Don't be a pussy.
Eh, right. Sure it might be tighter, but in no offense to you, i dont know what kind of loose girls you have sex with that you must use the asshole or what are you packing (neither do i want to).
I personally find it alot more enjoyable to use the "bidden" hole as you call it.
And it surely is not about whats forbidden and whats not (and if thats the deal, thats more elementary than i thought) I also never said someone fucks them just because it just so happens to be the one and only place that emits fescies in a human body, but then again the fact remains, you are dipping your dick in the only place that traffics fescies and when doing so thats the turnoff in it for me. its not about being a pussy or whatnot and if your weak idea of someone not being a pussy is fucking a girl in the asshole, then i guess you should really take a look outside and get back to reality.
you see some people nailing their penises into a woodplank, would you be a pussy if you dont happen to get anything special from it?
some people like gagging women with their genitals, yet again are you pussy if you dont want to do so?
The only reason why I would ever have constant anal sex with a woman among the "basic stuff" is if their lovelife demanded it and they were my partner at the time. I've had this once and I didint loose my mind over it but can't say I honestly enjoyed it more.
Its not about chickening out about anything, it's just what people prefer, and when I meet something that I just dont understand (example, feet fetishes) I question them.
