There is only confusion if it confuses you, but you sound pretty sure of yourself. One of my buddies from the WoR knew he was bi, and that worked for him and his wife. They were both completely cool with "It". Cuz there is no "It" if it's not an issue.
For some of us, it was a struggle to figure out if that's how we truly were/ felt/ are? For me , it was thinking i was bi when was truly gay. So no matter what your sexual inclination and as long as there is no disconnect between what's in your head and where you are in your life , then its all good.
Oh course there is bi, generally there is a great pull one side or the other but it is clear we cant generalize for everyone.
If you are comfortable and accepting of both spirits, then others will be too. If not - F'em, or ironically probably not. Some guys struggle with accepting the not so str8 part and that's where the issues can lie.
the best answer i heard was 99.9% of people are straight, gay or bi, the others just not interested. One study said that shown porn, most gay men are only aroused by men, str8 men by women and the bi group showed 3/4 had the same arousal pattern as gay man and the rest like heteros. http://www.nytimes.com/2005/07/05/health/05sex.html?pagewanted=all&_r=0
It's just about all of us accepting whatever is in our heart and head and going with it. Friendship, compassion and love are all way more important than labels anyway.
Thanks for unconfounding the dichotomy
