Yeah, I get touchy guys in the store, mostly they don't bother me, but a few have gotten creepy with it. I just pull back a little and so far, they haven't gotten offended.
The whole guy thing being interested in me has been weird. I'm fairly shy and I really don't want to risk dating anyone when so many people know I'm trans. I know what they would say about the guy.
In your situation, I would just not worry too much about it unless he tries to pursue anything further.
