I have like "boils" always appearing around my groin. I am a 19 year old male having unprotected sex. I have been tested in the last 3 months twice, and no STD's have been present. The boils sometime can come to a head and puss and blood will come out sometime. They never come to a head to be bust or lacerated. They're mostly hidden under the skin.
Also, my penis has been very dry lately. Is this signs of an STD or another infection?
