Hi my friend recently discovered a few white pimple-like bumps on his penis. He stated that they do not hurt, itch, sting, tingle, burn, etc... they are just there. He tried to pop them but they wouldn't. Its sort of like a blackhead but white. What do you think it would be? I thought it might be a yeast infection because it doesn't sound like herpes or genital warts. Need Answers
