Now i have these red/white bumps there, and don't know how to get rid of them . I know its not an STI as I was not sexually active when I first noticed the spots. I have put Antiseptic Cream (SOFRAMYCIN) on the spots but I think it just makes them more red. Is there any cream or ointment that I can be buy to fix this, they arent sore they just look really bad.
