I'm bi, but did not know it until after I married as the hetero I always believed I was back in '97. I believe in monogamy, and in the commitments my wife and I made to each other at our wedding. I don't believe I need partners of both genders for sexual fulfillment, but simply that I'm wired for either. The last time I completed a Kinsey worksheet, I came out to a 2.14 on the 0 to 6 scale, so I lean slightly to the hetero side.
I also moderate a community for GLBT Christian furries. Umm, I guess that's enough for now. ^.^
