My bf has what looks like a pimple on his penis its only one and its white?

what could that be|||It could very well just be a pimple. If it starts to look kinda like cauliflower, it spreads or he stats to get more of them then he needs to get chcked out by a doctor. Until you know for sure, I would suggest either abstaining from sex, or using condoms|||consult a doctor!please!maybe that wont harm but thats what the best you can tell him!dont stay away!
