Hi Doctor.. A few days ago I had discovered a pimple on my penis. It was in the middle and well I popped it, The puss and the blood came out so I went to wash it. about like 1-2 days later it was still there and well more fresh puss and blood so I decided to pop it again, but up till now there's still a bump on that area. Could this be any disease? I hope its nothing serious. And I got unprotected sex a few weeks ago. Also I would like to ask a second question how can a condom with I open up like slip of from my penis when I am having an intercourse? Is it because i kept it for too long but its not expired.
