question: hello, I am a 20 year old male who is experienceing not really red bumps per say but red spots on my penis shaft right below my head. only 3 spots anout 2mm in diameter.They do not hurt, no itching except when i start sweating alot and no discharge. i have been dating my gf for 5 months now and i tested negative on my std test a month ago. we do have unprotected sex could this cause the spots? They are not wet and are going away now just kind of dry skin now? please help
