My suspicion, however, is that many people on the "severe" end of the spectrum do crave some sort of sexual/romantic experience but don't end up going through that experience for whatever reason, but I could be wrong. If this is indeed the case, I want to know what prevents them and if there is a way to allow more people who want that experience to have it. The sensory could definitely be one factor but maybe there are other ones.
I personally think that it's pretty obvious - autism is directly characterized by impaired social interaction, and the development of romantic relationships relies almost exclusively on the subtleties of social interaction. Those who are on the more severe end of things often have other significant challenges to overcome as well. As you mentioned, if someone is nonverbal, it would be extremely difficult to form a relationship with someone if it is a challenge to even communicate effectively.
I'm on the mild end of things, and all of this relationship stuff is already painfully difficult. If I was on the more severe end, I imagine it would be that much harder.
