I am out to a few friends. I tried to have a discussion with my very religious parents about polygyny and polyandry in other countries and also biblical contexts and they seemed to think that it was only good if it was a necessity (ie, population inequalities in which the male to female ratio was abnormal--they are strictly against homosexuality). I mentioned that there was a world-wide male to female disparity, but didn't really feel comfortable going any further.
I think my bisexuality would hurt them and they would not understand my lack of jealousy if my husband were to fall in love with another person and vice-versa (female only, in my case).
My father has recently shown me that he has bigoted feeling towards homosexual people and since our relationship has not been close, I fear that any admission I would make about my relationships would sever the few ties we do have.
