I'm glad you brought the awkward topic up first. I know "hypersexuality" is a symptom, but defining hypersexuality kind of puzzles me, because I'm sure it varies from person to person. I think what you're describing it likely normal for mania. Sometimes when I'm manic I don't even have to touch myself. The thought alone is enough, and while I'd normally consider myself straight, I've thought I was bisexual while manic; not to mention, I'm far more adventurous as well. Don't want to make this TMI by going into the specific details, but I want you to know you're not alone in experiencing this!
