I'm a college student and have been talking to this girl for some time. She's the kind that just likes to toy with people and get attention. I found out she had sex with two teachers just to get good grades, and yesterday she showed me her tits. Now I understand that she does this just to mess with me, so that I run after her. For a couple days now she steers the conversation to a sexual subject and keeps on provoking me.
In a situation like this, should I defuse these situations or just escalate and go for it?
