I totally disagree with what Kristie said.
Yeah, I disagree. Maybe not totally, but here's my take. Honesty is great, but there's a difference between being totally honest, and sabotaging your chances right from the start.
Joe was flirting with this girl, and getting somewhere with her. Then he
decides to open up and tell her he only wants sex. If she asked, then I might say yeah, go ahead and tell her, but he went out of his way to bring up this information. Would Joe also be right in describing how he likes to masturbate, and the color and texture of his latest dump? That's honest too, isn't it?
All I'm saying is that you don't have to volunteer something like that until it comes up, and even then, you don't have to put it in such a way that it makes you look bad.
