who knows?
I do believe sexuality can be inborn and I do believe it can often be age related. Sexuality is so complex, i simply will not view sexuality in forms of absolutes. Sexuality is more of shades of grey than black and white.
I do believe sexuality is born into you, but I cannot dismiss the fact that some middle age trans women told me they are sexually attracted to women because that's what they have been used to and were raised into it.
While you may think that logic is wrong, I cannot invalidate their feelings on their own sexuality.
Besides, I do not think being a lesbian is a bad thing. It is what it is. I am neutral on the subject. If you're a lesbian...awesome. If you are straight...awesome. If you are bi, pan, a, omni, or anything else...awesome.
