The means I've used in the past is to just tell a girl, "Hey, you're really beautiful." But I've been told that that's creepy and makes you look like a rapist if you do it with someone you don't know really well. I have a lot of trouble building relationships, and I also have a lot of trouble expressing my feelings for someone. Sometimes I'm just so captivated by a woman's beauty that I have to express that feeling, but I don't know how. Flirting seems to be something only women can do, because if a man does it, it's seen as predatory behavior. I need some advice from people who have been in successful relationships. How did you express yourself initially?
