Is it normal for anal sex to be painful for a guy?
I had anal sex for the first time (giving). My female friend enjoyed it. And I did too, to a certain extent that is.
It felt like about 4 inches into her rectum, I could feel my penis sliding through the bones in her thigh / butt area.. She is quite skinny so the lack of fat around her bones may be the reason, I'm really not sure because I have nothing else to compare this to and can't find anything else online about it. Is this normal?
