Pimple like bumps on penis.

Patient: I am a 19 year old male and just recently in the last months i have noticed pimple like bumps on head and shaft of the penis.. they dont hurt, pop, itch or anything until recently. there very little . less then a centimeter.an until now they have caused no problems but last night i noticed they were open and stung when touched. ive been tested twice since they started and everything comes back negative. do you have any idea what they could be?

Doctor: Without taking a look at them its hard to diagnose what they are exactly. I would definitely make an appointment with yo ur family doctor to go get them checked out as it does not solve normal.
