Up to you, but in my non-medical opinion… let it heal, dude. It's like how you wouldn't want to scratch an itch too much, or you'd make it worse than whatever caused the itch in the first place.
would it be bad to have sexual relations b4 it heals fully?
Part of your question got censored, but I assume you were referring to some rough oral sex? If so, you might want to tell your partner to go easy on it next time or do it more quickly. Just let it heal for now. It might take a few days. The dried, dead tissue on the surface should eventually wear down, so you'll feel the usual amount of stimulation from friction.
The surface of the glans is mucous membrane, not skin, and it can't take quite as much punishment.
