Bisexuality Support Group
Bisexuality is a sexual orientation which refers to the aesthetic, romantic, and/or sexual attraction of individuals to other individuals of both their own and the opposite gender or sex. Most bisexuals are not equally attracted to men and women, and may even shift between states of finding either sex exclusively attractive over the course of time.
Am sorry you're going through this and can only suggest asking the wife if she'd be willing to do some counseling with you. I know its dreaded (therapy) but its a good way to get a third party in there to moderate discussions with your wife. esp for touchy subjects like this
find a doc who is counseling not clinical, and specializes in couples/sexuality issues. I was able to find a counseling pysch who specialized in alternative sexual identities too so she could have patients who were gay/bi and who felt comfortable with her.
Maybe someone like that so wife can get educated and learn that this is normal for a bisexual?
Hang in there!
