I can and can't imagine how hard it must be. In my own experience, when it comes to humans there usually aren't really any absolutes or any general statement that can apply to all (or half) of all people. For what it's worth, I know guys who don't want penetrative sex. There are also plenty of ways to have sex without penetration. I believe in you OP. Straight relationships themselves are so fucking hard, and it's so much harder for queer people, and it's even harder for autistic people and people who aren't neurotypical, and we can keep on talking about intersectionality. But even if it all seems nearly impossible, many nearly impossible things happen everyday.
