if the woman i'm with is not enjoying performing oral, then i'd rather she just stop. there are plenty of other ways for two people to have a good time. sounds like the situation with your friend. i love giving oral though. i love having power over another person's orgasm, so to just sit back and let a woman take care of me is timing out on what i like most about sex. so if she's not making me go nuts, i'll usually move on to other things with them.
