I think this belongs to adult sexuality. On one of my other questions I got ask on my flirting, then it came to me that I have never flirted before and don't know how (very shameful), so please answers me this: what's the best way for a guy to flirt?

Be funny! Tease a little, then back off. Seem interested in same subjects. Play a little but do not come on strong. That'll blow it.
Always keep 'em wondering. (I think he likes me but not sure, hmmmm)

Wow... how do you explain flirting?

Flirting is keeping things light. It's innuendo, it's a wink, it's well timed comments. It's letting a girl know that she's interesting without actually SAYING "I think you're interesting".

A goof flirt doesn't take themselves seriously, nor does he let anyone ELSE take him too seriously. Flirting isn't trying to get someone to date you, necessarily. It's showing the fun, teasing side of you to other people.

A good flirt has good eye contact, confidence in themselves, and a way of talking to people that makes them think they are the center of your attention.
