3 days, just to see how it felt.
Turns out, I wasted 3 days where I could have came every day.
Once, after a motorcycle wreck, I was catheterized in the hospital, pissing through a tube into a bedside bag. My girlfriend came in and while she was there, I got hard. Not a good thing with a catheter in your dick!
Once I got it out, after about 10 days, I just had to shoot quite a large load. My girlfriend helped me out in that regard! Sex in a hospital room is very risky, you never know when a nurse, or some other hospital worker will suddenly walk into your room. You can't very well lock the door! At least we closed the curtain, giving us a bit of privacy and buying us a couple of seconds to act loke nothing was going on!
I was in the hospital for almost a month, so I waited until late in the evening to rub one out...every single night!
