Okay, first off...theres a big difference between a lesbian and a girl that is bi-sexual.
I'm kinda bi. I've fooled around with a few girls over the past few years and only had one full-encounter sexually with a female. But, just like April, I will NEVER give up cock for pussy! NEVER! LOL
If a girl is bi, she likes men and if you think that because she is bi that that is the reason why you aint gettin no play, maybe you got no game! LOL

Or maybe you are afraid and intimidated that you wont satisy her like a woman could. Which, alot of men think (when it comes to bi women).
Act cool..be yourself, and after a week or two, ask her to bring a friend !

LMAO!
