Ok I was masturbating and I noticed when I was done I had a little cut! I let it heal for a couple of days! I engaged in sex without it 100% percent healed and almost immediately after their were bumps all around it like little pimples! Is this a infection from not letting the wound heal or is it a std! They don't burn or ooz their actually scabbing up, just want to know sum input!

Sex with or without a condom?

You daredevil. Risk your life for a few moments of passion.

You took maximum risk.

See a doctor asap. Scabbing would have me sitting outside his office door waiting for him in the morning.

Time to get tested for a STD, and yes often they may go away, and stay away for a while, but still causing harm.
Most likely not related to cut, but to a transmitted problem.
