From one Bipolar lesbian to another: I started laughing so hard, 'cause the moment I saw "Okay, right...so I have a pretty big sex drive" I thought, "Try having Bipolar Disorder." Ha!

Casual sex isn't something to be ashamed of, and tons of people engage in it. I think it's only a problem if you're hypomanic during the sexual encounters and end up regretting them or hurting someone else. If you honestly don't think you'd regret a hypomanic hook-up, then go for it.

I think it would be okay for you to mention your desire for this other woman while you're sober. The worst thing she can do is turn you down.
