I resently popped a pimple looking object on my penis, it came out like a normal pimple, but after a few days it seemed to scab up almost like a crator like hole with a needle size hole in the center, and , the scab as gotton smaller and seems to be healing but now there's a lump? I don't know if this could be an std or what so please answer, and yes I am currently sexualy active
