Genital Discomfort. Caused this.

Hello, I have been recently diagnosed with Prostatitis caused by gram positive bacteria. I am under medication treatment. I started experiencing pain 3 weeks back then I've undergone all sorts of tests and they came normal. I didn't have burning urination but I did experience pain. Now, while I don't have pain but I feel some discomfort in my genitals. I also feel constant urges to Masturbate. My doctor said that the pain might have been induced due to Masturbation and hence I've stopped doing anything of that sort. But yet I feel the urges and I get an uneasy feeling in my genitals (which wasn't the case earlier or ever). So, I wanted to know the reason of this pain. Also, I wanted to know if I should Masturbation has any effects on prostatitis or any other reason that might've caused this.
