The other day I was talking to a friend who was very upset because he brought this girl home who gave him a BJ then she snowballed him (kept the cum in her mouth and spit it into his when she kissed him). She told him its because he didn't warn her that he was about to cum, so that was her revenge. I've always been pretty verbal during sex so I never even really thought about it before. But I guess most girls like the warning? I've never done anal but I would assume most girls would want you to ask permission before going there? So I'm just wondering if anyone else has any stories of revenge for poor sex etiquette. Or just rules they prefer to follow when doing the deed?
