Questions: Guy's Behavior

I've become friends with a coworker (save the lecture, it's just retail). I believe we both have feelings and that's where it's heading, but he's scared to make a move (severe insecurity and risk of work problems most likely) and so am I. And I still have some doubts, so I'd like feedback. Are these things he has done just something a guy would do if he sees you as a friend? I'm autistic (he is too) so I have trouble with this stuff :( We're both single by the way and are aware of that.

-gives a custom nickname, and petnames ("my dear" "yes maam" "the lady")

-sent a sleepy shirtless picture (not full body but the shoulders were showing)

-has told his friends/family about me

-does things for me even though it's not his favorite (taking pictures with me, watching my favorite show)

-subtle touches like nudging and patting the back, playfully touching my knee

-shares very personal life stuff

-wants to spend time with me (I always do the final planning though, we've hung out 3 times - seen 2 movies, and the third time took a walk then went to dinner)

-willing to drive 30+ minutes to see me

-told me he doesn't know when he's being flirted with and also is scared to touch women without explicit permission

This sounds so obvious typing it out but I'm still conflicted. Looking primarily for male feedback but will gladly take anyone's opinion. I really don't wanna be the one to bring it up to him, so maybe also some tips on how to clearly show him I'm open to taking it further?
