I consider myself straight, however I have shared bi experiences with my wife and both men and women. I guess I'm what you'd called incidentally bi...since I don't have any desire to be with a male one on one, I don't consider myself gay in anyway, but instead I am as they say heteroflexible. I am not attracted to men, but can enjoy sexual contact with a male in the context of a threesome or a foursome. Homophobia being what it is among most men, this is admitedly a touchy subject. Nonetheless, I've found that most men we've played with have had at least some bi experience. I think that for some, sexuality is as much an activity to be enjoyed as it is a committed lifestyle or "preference". As an analogy, how about this...my wife enjoys hiking in the woods, I am not an outdoorsman in any way shape or form, but sometimes I go for a hike with her!
