How normal is it to feel pain when orgasming?

This is something that always happened to me since I was like 13 (I am 28 now). It doesn't always happen but I am starting to think that maybe it should not happen at all. It got worse a few years ago and then it got better. Now it doesn't hurt at the moment but it causes a certain type of irritation right after that makes me wanna pee more.

Edit: Forgot to mention that I am a man.
