This usually happened to me, and over time it just stopped happening as long as I didn't get too spun, and then the problem was maintaining a hard on not getting one.
Stims are strange as they boost my sex drive through the roof and at times can give me a rock hard boner and I can paint the walls after i pop..problem is, most of the time my boosted sex drive comes with a dead dick..liquid cialis can help but only half the time..
No clue how people fuck for hours on meth..they must be using that erectile booster stuff you shoot into your penis. Lol
