A single male here:
I have chatted with a few single bi-females in my area and actually met three of them. Played with one, scheduled to "meet" the second privately next week.

To me it's the same as meeting people any other way, express an interest in the _person_ if you have an interest, don't be pushy, be polite, and don't "expect" anything. I "hope" to meet more females (and couples too), seems like we would all like to..... Maybe I am too patient
