Dating an Older Man

Okay so i know this has been on here before, but i didnt pay it any attention because i was like "no way i'd actually date someone who is significantly older than me" NOW im kinda dating a 31 yr old and im 18 so im "legal" but like as awesome as he makes me feel and as respectful as he is to me, (like im an 18 yr old virgin, and he's totally okay with it) I get so nervous because in society our relationship is totally frowned upon, but we make each other completely happy. So like wtf. I want to hear what yall have to say, i just needed to let this out. K thanks girls!
