GUYS: so my bf and i are thinking of having sex… but…. PLZ HELP!?

so my bf (17) and i (16) are thinking of having sex… but i used to have acne on my back and chest… it started to go away cause i got some ointment and stuff, but u can still kind of see some dark marks and an eneven skin tone…. would this bother him and make him think i'm gross, or would he not really care?
