well the gist of it is, i have always had chemistry with a friend of mine but never did anything about it due to the fact that i had a girlfriend at the time. I've never been intimate with her and i've searched the forums on the difficulties of attracting a known friend. The kicker is however, that she's bi-sexual... so i'm curious how i can approach this or even if i should approach this differently because of this. Anyone?

dude. it's the same. just because she's bi doesn't mean she thinks much different than straight girls.. and unless you have experience with bi girls in the past then don't try anything funny on the bi subject as tonality can immediately kill your chances permanently.

75% of the girls i've dated have been bi. treat them the same as you would anybody else.

the one way to relate is to ask them if they participate in the GLBT community and show/feign interest in it because you've grown up fairly ignorant of the lifestyle.
almost every bi chick i've closed has been due to the fact that i've shown interest in their lifestyle and want to know more about it.

if you need help with situations/topics feel free to ask as i have a plethora of stories/situations i can run you through
