I am interested in gay sex, but not a relationship with another male?

I want to let people know I am curious about same sex relationships. I am not gonna jump into one. Throughout my life I have been mainly focused on women. Recently I only get off to the thought of gay action instead. I think the porn in general has desensitized me. So if I lay off the porn and build my libido back up, can I get that juice flowing for the women again. I just think that is the case. I have been mostly bi all my life. But I don't see myself marrying a dude. I wouldn't mind fooling around and having sex with another guy. But I want to make a family and home with a women. Its an instinct I am trying to get back. I now know how bad porn is. Lucky I am 18, I think I can change myself for the better. For gay men what do you think of when it comes to my loss of arousal for the opposite sex. I find women extremely attractive but I need to find out how I lost my edge and getting it back.
