Also - is he a serious Catholic? My husband is quite shy, and old-fashioned, and a serious Catholic (as am I), so he was very hesitant to initiate any physical behavior. I just sat back and let him get comfortable with me, and all things came along in good time . . .
Hope it goes well! (Although he should
have asked before bringing the guys . . . sounds good otherwise!)
Then just confront him about it. You don't want to be led on for too long. Nobody stays young. :)
But do it in a way so you can stay friends!
Then again, maybe he's just figuring you out. Getting to know what you're like alone and in public to see if he really wants a relationship with you. :)
Man and woman - the eternal dance! :^)
