First, sexuality is not a nasty thing, as we were told. Any may have had an homosex experience, at any age, and I won't blame my family, their teaching, because it was ME who made my choice.
I reacently went to a PT meeting and this topic raised (one mother needed answers). Some gave his opinion, based on books, perhaps hiding anything from his personal experience (I'm not to judge) but he said, mingled with more things, that "researches have found and ADN code related to the gender we cling...". When he finished, I quickly said: "If that were true, we can easily CAN BLAME GOD"... And obviously I CANNOT blame God for my decisions, my choices or self will. Sexuality is deeply connected with MY CHOICE, as an individual, same way as any sin. If I'm not told what a sin is, I surely will behave like a dog in the street, smelling here and there and, being a dog, finding a female dog (just to avoid the word you know) I wouldn'd mind do in my thing where another dog licked or left his "seeds".
The very idea of misbehaving like a dog is sordid and nasty. Living sex, without LOVE is much worst. And I'm convinced BOTH coexist in God's teachings.
Love is superior than sex. Sex is very well oriented when we are in the correct way. Look deep in the eyes of those who made wrong, have lawfully made another sex choice, and compare who is happier.
I know nasty things in my family. Sometimes I was sexually molested or I myself did the wrong thing, and I'm happy I don' t forget my mistakes, just to avoid repeating them, but I blame no one else, but me. Those were my wrong choices as an individual.
