So I am a 19 year old girl in an LTR (with a man) but got permission to experiment with a girl. I have this really pretty friend who I know is not adverse to the idea of bi-sexuality. The problem is that we haven't been really close lately (both been busy, don't share classes). I'm working on spending more time with her, but I will feel a little disappointed if I can't make anything at all happen (even a conversation on the subject or rejection) before the end of the semester in 2 weeks. Any advice on making something happen here? I'm totally new to trying to pick up women and could use some help.

Edit: the reason I know she is adverse to being bi is not because she is open about it or anything, she is obsessed with this female underwear model. when watching the VS fashion show I asked if she would go gay for her and she said she would not just for her. Hope this helps people understand the situation a bit better.
