Do i have to contact the doctor or can i just leave it? I get little pain in the left side of my bladder,
"This is completely normal ..there is no such thing like retrograde ejaculation as per my knowledge.."
Wrong.

Noah, it's unlikely that you are experiencing retrograde ejaculation, it's pretty uncommon, and usually isn't seen too much in young men, especially young men without some kind of history of a medical issue or surgery that would put you at risk for it.
For the most part, it's harmless if that IS indeed what you're dealing with. Either way, it's a good idea to talk with your doctor about this, so he/she can rule out any issues.
Good luck!
I get some burning pain when i pee.
