Im not sure if this is a unique problem, but im a 18yr old virgin. However when playing football during the week, i came home and needed to urinate and number 2(not 100% sure what the correct term is) when i felt my penis stop urinating. I looked down andthe bottom part sort of formed in to like a bubble and to be honest i thought it was going to burst, i squeezed and urine started to flow out of my penis, but then it just shrunk and was literally tiny, i felt a bit worred and then even got even more worried, i looked and there was lots of small white chunks all round the side of the inside of the toiled. I decided o take a shower and thankfully it returned to norma but after 10 mins it shrunk in size again to the tiny. I decided to see if i could still masturbate but it looked like my penis had sort of become 2 parts but yet and all i was able to ejaculate with no problems but at the top of my penis it felt a bit wierd, i dont think it was a spot but im not sure, i havent pulled my foreskin back that far ever so it was painful when i tried to look and stopped, everything seems to be fine at the moment but im just a bit worried, should i see my GP or is this normal?
It is possible you may have some sort of infection. It would be a good idea to follow-up with your personal physician.
