Scratch/tear after intercourse, std, infection?

i think that my boyfriend accidently scracthed something in a soft tissue with his nail or teared it with his penis too, but I only felt irritation after intercourse. Then I was bleeding light blood for a bit and skin has peeled of a bit. the white part could be just the tear or something worse like infection? the protection is always being used I doubt that is some kind of std. could it be vestibular papillomatosis bump scrached off? thanks and what should i do , get it checked out or just let it heal? it doesnt itch but is uncomfortable and i feel it.. thanks!

get it checked out
