You're awesome man and you have my infinite respect. Like you, I have fathered biracial children. 2 with one couple and twins with another and I feel honored everyday for the opportunity because it was in no way an easy discussion. Both were planned. Met the first the first couple at work and the second couple through them a few years later. They both wanted children but the husbands have a medical issue that made them infertile. The difference is I'm not as involved in raising the children and that was a decision we made since the couples wanted to be the parents and I was pretty young at the time. Their families think I was just a selected sperm donor. They don't know how intimate we were but both families accept me as part of their families. The ******* call me uncle and I come to every birthday.
