I’m not going to get into the middle of all this and ask why you’re do all this research but I will answer your question based on MY experience and mine alone. When I’m in my manic stages I do get hypersexual and sometimes it’s worse than others and sometimes it’s manageable because it’s simply thoughts.

Since I’m in a relationship I have to find ways of dealing with this without jeopardizing my current relationship. My girlfriend with help when and where she can, I write heavily sexual stories, read heavily sexual stories, watch porn, or whatever I can do to keep faithful to my girlfriend BUT get all of this sexual urges out.

Again, this is just my experience and I do believe that the diagnosing should be done by a professional not close friends or family. If he is depressed and/or bipolar (something I can’t seem to figure out in the post itself) he should probably receive professional help for it, but he will only do it if he wants to.
