From what I have observed over the years and also being a guy myself, I have found guys fall into 3 major categories when talking to women.
1. Will do anything to bed the woman.
2. Is socially inept and doesn't know where to start.
3. Wants to genuinely offer a complement with no ulterior motive.
This being said. 99.9% of straight men have a common sub-category that sex and boobs =
.
