LMFAO. I'm laughing so hard right now how random. I'll try to be serious though.
From a guys POV;
I can see why you wouldn't.
But keep in mind in most pornos they thoroughly cleanse the inside of their asses as well as bleach em.
So I'm sure no one is really grossed out knowing that.
However, If you were to just have a one night stand or even a girlfriend of a few months and she asked for anal?
eww. don't do it. no no no no no no no no no.
I feel like anal sex is one of those,... "we've been married for ten years" kind of comfort.
If you can take a shit in your master bedroom's bathroom, with the door wide open, and your partner laying in the same room,...
then you two can have anal sex.
From a female's POV;
No. Dicks do not belong in my ass.
That's it.
