I was born & raised as a Christian, and I basically align with Christian values as far as the Ten Commandments, etc., but I am in fact an agnostic. I do not go along with much of any of the Christian thoughts on sexuality.
Sexuality is something that I believe has been twisted, and distorted, and completely SNAFU'd by organized religion. And of course Asperger's and sexuality is another whole can of worms. Add the two together, and you have a ball of confusion the size of Jupiter.
Most religious opinions on sexuality probably come from 2000 years ago, when we needed rules like that to prevent the spread of disease, and to prevent abandonment of pregnant women and those with small children, by mens' wandering nature. My view: Sex before marriage is A MUST, or how do you ever know if you're compatible, of if one partner has some sort of unsolvable sexuality issue? Cheating is a definite NO, and of course age-appropriate conduct is a must. And Gay/Str8/Lesbian is all perfectly equal and perfectly OK, as far as I can see. Religion puts a guilt trip on any unmarried or same-sex relationships, which I think is not God's business, nor the government's, nor the neighbor's, nor mine.
