About pain in the balls & prostate problems

So, i just get urges, or sometimes my mind goes where he wants, and it ends by giving me strong urges and pain in the balls.

Let me explain the situation very fast:
Now i go over a week clean of PMO. I decided to celebrate it with some real sex. The problem is, yesterday i was going to do it but me and the girl just dont coordinate well and passed it to today. So, today we are not doing it, for personal reasons.

During this time, i had hard pain in the balls and i thought on masturbate just for reset, i read that this type of pain can be very bad for the prostate and bring future problems.

The pain is obviously for prostate irritation due a blood overflow.
Not blue balls, but red balls

So, i should evacuate now or just keep the pain?
