My embarrassing body acne

So, there's this guy, who wants to date me. He likes my face because I cover most of my acne, and wear lots of eye makeup to distract from the rest. We've only known each other for a week, but I can tell he's sexually attracted to me. The problem is, I have butt pimples, an ingrown hair under my arm, and acne all across my upper back. If I don't show him my face and back without makeup, am I leading him on? When I'm ready to tell him, how should I explain it?
