What turns a guy on?

just wondering. It's kinda driving me crazy, that I have no clue how the male mind works. What turns guys on? What's the best way to ask a guy out? WHAT GOES ON IN THEIR HEADS??? Like I said...I'm curious. And frustrated.

Be a little tease.. Spontaneously say some cute things... Those work like magic.

Tough question...You want to be a tease like Apathic says. BUT you don't want to be TOO hard to get. Most guys don't like it easy yes..but they don't want to always do the chasing. Maybe a little aggression could come in handy. That's all I know. I would love to see what anyone else has to say
