My opinion is to just do IC right now, get some time under your belt so he is comfortable around you, and himself, before MC.
As far as affection...maybe if your initiations are just more casual touching, like on a shoulder, or hand at first, but anything more maybe let him lead for a while. We guys can be extremely sensitive to rejection though, which would make us initiating a bit more difficult. I think if you paved the way with those small casual touches, that would alleviate that fear. Assuming you yourself are at a comfortable stage, naturally...
This is tough, you just have to feel your way along I guess.
Hang in there!!
