From what i remember, her case was more of a harsassment one where it was persistant. If a woman makes it clear that she doesn't like something then the guy should stop.
But that isn't what i'm talking about. I mean just talking about any aspects of sex in public. Women especially are often so shocked or disgusted by a man showing any sign of sexuality. Especially if, God forbid, he has a partner already and is not talking about sex with her.
