So I just started seeing this girl about 2 months ago and we've hit it off VERY well. On our third date she mentioned that she's been with a "female friend" only a couple times and fooled around a little but never did a whole lot, she's attracted to women, just not as much as she is to men. I'm a very accepting person, so I thought about it for a moment and said I wasn't bothered by the LGBT community (which is true, I'm completely straight, but don't see a problem with anyone different). She has made it perfectly clear that I can trust her, we both have A LOT of trust in each other, I think that's why things have been going so well; aside from the fact that we have a lot in common and seem to be meant for each other in the bedroom. My jealousy has been almost non-existent in this relationship which is new for me, so the trust is strong. She's been completely open with me about everything, as I have been with her. However she asked me last week if I would mind if she experimented with another girl eventually, just for fun and to get the curiosity out of her system. I told her I'm not completely comfortable with it, she said she understands and would never do anything without my permission and would certainly never cheat on me.
The dual voices in my head have been fighting over this. My imaginative/loose side thinks "hey, why not, whats hotter than two women all over each other, plus it'll satisfy her curiosity and possibly get rid of future urges she may have". However the sensible/logical side thinks "don't forget, you can be a very jealous boyfriend, and this IS cheating, she's just asking you for permission instead. are you going to be able to accept the fact that she was with a woman while you two were together? And what if this opens UP future urges she may have instead".
Of course the decision is ultimately mine and hers, I am looking for some advice/insight from the female community. I may also ask this in the male forum as well.
So what do the women here think? And if there are any women here that are bi, that would be a big help!
EDIT: I should mention our ages are 25/26. I know that can make a difference in some circumstances.
