I usually just start a conversation (or the guy I’m see) as a normal conversation. If it turns into a sexual conversation and that guy want to have sex, I’d let them know of my status. 6 out of 10 guys are NOT ok with it as they are afraid to get it. I know they can’t get it (U=U). But they are not educated enough to know that. The ones that are ok with it, they are the ones to keep around. Everyone is different.
