First off, congrats on finding a gem...let's not lose it. When illogical urges and desires start messing with me, that tells me that I need a med adjustment. The past is the past...you're next is your new. If you start regretting or wishing what was, that'll taint the new and future.
Promiscuity and sexual longings are a signal to onset of hypo or mania. Every time I realize this...I tell myself that I'm just being silly and try to snap out of it. Of course, bipolar is instincts gone wild....you need a fix...IMHO.
Good luck!
