If you aren't in exclusive relationship with neither one of these men, you can talk to 20 other guys. No need to feel guilty. Have you met any of them? If not then for sure there is nothing to feel guilty about.
The guy who tends to be sexually and otherwise dominant (or so he says, rolling my eyes)sounds rather strange to me. If he really just wants to be friends as he says, he has no business to even comment on if you talk to other guys or not. He sounds fishy to me.

Bottom line there is nothing to feel guilty about. He isn't your boyfriend and you don't need to disclose who else you are talking to
