Actually I tend to think the benefits of being heterosexual occur here on earth. I don't think God really cares that much about our sex lives, but I do think that a secure and stable marriage and children are two of lifes greatest joys and if you are homosexual chances are you won't have either. It's also a very unhealthy lifestyle both emotionally and physically. Men and women are naturally complimentary to each other. Men and men or women and women are not.
Big time wrong on one of your points my friend. God cares very deeply about your sex life. If you think otherwise, you are reading the Bible with a very big eraser in your hand.
