okay, what is it about anal that guy's find so attractive? I can't seem to wrap my head around it, that's not what that hole is for so...Anonymous
If you want to take that approach then you should be asking why people use anything except a penis and a vagina. I mean, nothing else comes into play if you’re speaking strictly about biology. The primary purpose of the mouth is not for oral sex. The hands are not for giving yourself or others stimulation. Yet no one seems to mind when those are used for sexual activities?
But getting back to your question, I wouldn’t say there’s any one clear cut reason. I imagine the taboo nature behind anal sex can be a big reason for a lot of people. Also, just the nature of curiosity behind the whole experience whether someone saw it in porn or has just always wondered how it felt.
Personally, it has been more of a curiosity.
