How do i find a bisexual around where i live?

there any websites?

really Almost Any Girl You meet will Be Interested in Being with another girl so maybe one of your closes friends are bi and you don't know it... so just go for a girl if you get turned down try again.

is that really smart..you say your 6 months pregnant and you want to have a 3 some...that could wreck your relationship..and thats not a good thing to do when you have a child on the way..
