Yes, my boyfriend is definitely on the spectrum (although we don't discuss it/label each other). Sex is well... Like how he is in every day life I guess-intense. Before, when we were just friends, he wouldn't even hug me!
I initially thought he would be grossed out by touch and intimacy as he is very tidy/clean/OCD. But he is surprisingly relaxed and playful with me. He said he loves being with me-however I always need to initiate. I don't know if that is out of politeness or what. I always hug him first, he responds warmly and doesn't let me go until I tickle him
All it takes to get him going, is a soft kiss or hug -and he's like a tiger
What can I say, its nice. Maybe someone else would find his behaviour odd. But I don't.
