My attitude is the similiar to DePressMe. I worked in a mainly male dominated work environment, most of the males there still had a cave man attitude. Even so, with very few exceptions, as long as I was clear where my boundaries were, they respected them.

I did have close male friend that thought it was funny to try to step over those boundaries. He really meant no harm so when he did I'd smack him on the side of his head. I didn't get fired for hitting him, he didn't get fired for his mouth.

Maybe at your next job it would be better to keep thing strictly professional. I can't tell you how many people I know that have been fired over a stupid email that was not received in the spirit in which it was sent or sent to the wrong person.
