Supersizeit:
I agree completely with that point of view.

It sounds like you have a very healthy “injury/response” mechanism going on there. I don’t think you could actually get any shrinkage though, unless you did some unthinkable injury that caused a tunica breach, which is a different game altogether.

I think the take home message is that if what you’re doing is working then keep doing it, and screw the theories. Fibrosis isn’t bad exactly, it’s the result of a necessary response, but we want it to heal in the optimal way and without unnecesary extra tissue. To take an absurd example, it would be bad if say your left arm formed adhesions with your right leg, but healing a scratch with the same process on say your elbow would be good. It’s the difference between healthing the scratch and forming a scar on the skin, and healing it with no visible marks. Massaging the scar (or therapy of choice) could help tilt the process towards desirable asthetics, but abstaining or overtraining it could either not help or possibly even exacerbate it. I’m not thinking too cleary at the moment so I hope that makes sense.
Penismith has done some good work into this recently, and from that I’m forming the view that multiple shorter sets (especially in any exercise that entails occlusion) with plenty of massage/engorgement would be most beneficial (supplements aside).
