well, I do get off probably every day.
Well, all I know is that I drink alot of water and sometimes at night, and at about 6:30 am when I wake up, I have an erection and a bladder that feels like its going to burst.
I don’t think its too outlandish to think that while sleeping, subconsciously, you are holding your piss in, causing you to do a kegal sort of and hence getting a hard on. I mean, its not RAGING or anything, but its probably 75%. I can still take apiss as it probably goes down to like 60%.
