How long without cumming?

I'm pretty sure some studies have been done. I just don't want to bother looking them up right now. The prostate, like many glands has microtubules like inside the kidneys. It seems like a good deal to blow them out now and again. I know they tell old guys with BPH to masturbate.
 
I went six months without shooting a load when I was in basic training, airborne school and parachute rigger school. It was kind of weird when I finally did it because it took a long time.

In basic my detail was the urinals and showers. There was always cum in the urinals in the morning. Funny I never caught anyone.
when i was in the navy basic training....i went into the head or bathroom and jacked off......the others jacked in there beds. i like some light. they said they put saltpeter in the food to stop us from being horny.....it didnt work.
