You said you were intimate . I am aspie and I do think intimacy with aspies is different. I don't want to generalize and I have not had many sexual experiences at all. However, With aspies, I think, there is more depth, more meaningful touching, exploring, looking, less talking. .
With nts, it's different. You have to talk and say what they want to hear and say things you can't really think to say and mimic what is "supposed" to be because they cant understand unspoken language.
Of course, not all people are like this. There may be an NT psychologist who knows aspie-speak. But you said you pried, asked him to talk, etc. That is exactly what I hated about nt intimacy
and I am NOT even talking about sex. Even just the closeness involved with dating. With aspies, much more intense, less talk, less demands to be fake.
I would guard yourself with intimacy with aspies if you don't understand this The intensity may be more than you understand and you will demand words from him and explanations which will exhaust him. Just a few thoughts.
