Just let the record show, I was not telling her to have anal sex. I was just telling her of my experience with it. And it will not make you butt bigger!! A lot of anal sex can stretch your muscles and cause leakage, but an anal experience, every now and then isn't going to matter. Also "sin" is in the eye of the beholder. I am not a religious person, nor do I think its appropriate for it to be preached. I have heard also that men prefer anal sex over vaginal, who cares!! If you don't want to do it, then don't!! However don't look down on someone else if they have done it, and maybe liked it!! We can't please everybody!!
