Have you experienced frequent urination when you used to masturbate?

Alright, i am asking this question, because i suppose there are more people having this problem, than it seems. Lately i had some people write me letters and ask me about this, and does it go away, and how much time does it take to go away, and what to do, and other stuff like this. So what i wanna see is, does this problem occur often.
It is usually accompanied with anxiety, nervousness, urges to pee each 20-30 minutes.
Yes, i had this too. I don't have it anymore.

Now the comforting part is, that if you stop PMOing, approximately after a month it goes away, at least with me it happened so. But back in the past in when i used to PMO 2-3 times a week, this problem was with me almost always. And especially on the days when i had relapsed.
Another thing that i wanna say is, that sometimes if you have a wet dream, this reappears, but for short time, and not so strong, for example, today i had a WD and i urinate a little more than other days, and the color is transparent or little white.

Another question i have is, what do you think this is due to ? I mean what causes it and why does it happen ? Is it the swelling of the prostate, or something in the bladder, or something else ?
Thank you for your answers. ;D
