Is it an STD? help me, please... Rough spot on the penis

Hello, Three weeks ago I had a sexual intercourse, I used a condom, I did the penetration, but I removed it because I put it wrong and put it back on, I think it was on the right side because it was dry, only today this scaly stain appeared, it doesn’t hurt, it doesn’t itch and it doesn’t even urine falls, what can it be? it is kind of dark.!
