I'm not bipolar but I classify myself as hypersexual. I've been in that situation countless times. Though it's not the safest situation to be in sometimes; it's a natural one. Disgusting should be the last thing you label yourself. Be you and never be ashamed of who you are.
Just because it's something you wouldn't normally do doesn't mean you can't do it.
Some of the greatest things in life happen in a moment's notice; it could conversely go the other way also but I don't like to dwell in the negative side of things.
If you need someone to talk to in confidence. I'm at everyone's disposal
