Missed this one but feel a need to comment.
Apparently, everyone flirts to get on in relationships! Read Peta Heskell's Flirt Coach and it makes sense. "Flirting" is commonly construed as sexual or partner interests; in fact, flirting is what we do - we are nice to people, we smile, make eye contact, show our vulnerability a little, and work to who we see in front of us. That's what builds relationships and rapport! Flirting in the relationship sense isn't about coyly looking over your shoulder, lowering eyelashes or winking at the opposite sex - even with social flirting, it's about building rapport and finding things in common with the person you speak to. So yes, men too flirt and if you've ever been to networking meetings you can see it in action all the time as relationship/trust building. Women don't need to flirt to get on any more than men do...and we (women) don't try to in my experience to 'get on', we are more naturally interested in people and nurture relationships perhaps!
I don't know how to flirt... teach me Julie :)
