I've tampered with PE in the past year or so, but of course exercising on and off doesn't work so I'm going to go full on and do JP's 90 day routine, hooray!

My question however is that I didn't get the best cleanest circumcision, or at least it hasn't healed properly over the last 15 years or so. I've got these skin bridges (that thankfully don't connect with the penis head) around my shaft about a third away from the head. Just makes me so mad how crap of a job they did.

Should I avoid jelqing/stretching over the skin bridges in case that area starts stretching ('cause it's already rather tight there), or does PE only work if its done all the way up the shaft?
