I wouldn't recommend it.

I did it because I heard that your balls were supposed to physically hurt if you didn't nut for a while so I wanted to hold my nut until they started hurting.  I ended up holding it from the 18th of July to the 19th of September, and it was absolutely horrible.  I became irritated a lot more easily than usual, I couldn't focus on anything, I was excessively unproductive, and I literally could not make eye contact with a remotely fuckable female without immediately getting desperate for her vagina to be wrapped around my penis.

I gave up after 2 months because I didn't think my balls would ever start hurting before my life started to become ruined.  It's been over a month since that humongous nut, and now I am actually addicted to masturbation far more than I ever was before the no nut challenge that I went through.  I'm still trying to recover myself to control myself a little better like before.  Literally I used to be a happier person before I did the challenge and now I am slightly less happy.
