You won't hurt yourself if you don't do anything extreme. By extreme, I mean, hanging 50 lbs off your dick or clamping for 2 hours a day.

Jelqing is actually beneficial to the health of the penis - the added growth is just a "side effect." Don't use too much tension and start with only 5 minutes per day. If you notice your erection is flagging, then reduce the time or frequency (i.e., every other day, or every three days).

The main thing to remember is to work with a penis that is between 30-70% erect. The only risk with jelqing is when you jelq at higher erection levels.

Good luck.
