I recently have had sexual relations with a new partner, I am a man and hetero sexual, I am more of the long term relationship type, but after 2 weeks I have some sort of zit that was growing on my penis, it was quite big and it had a white head, it was painful so I poped it, and some fluid came out, it is on the skin, but there is still a bump, I have read through the forums and I must say I am starting to have a cold( i'm in montreal and we just started to have cold weather) so what should I do? I have blood test taken twice a year. Please help, our medical system in montreal is overloaded, so I do not want to waste a doctors time if there is no reason to panic.
