Once girls get to the age where they have sex a little more often, they start to know whether or not oral is something they like. If they don't like it all that much, they will probably say they don't like it that much and the guys won't do it unless she wants to try it.
I can see how the idea of being down there on a girl could be a turn on for the guy.
I've heard some girls they like different sorts of things done to them down there so I can't really comment on the 'right' way to give oral.
when you talk, i dont care what it means, shouldn't just stare at you, should i?
