I noticed that there hasn't been a lot of talk on this site about warmups before PE, so I thought I'd say something. I've been into PE for several years now, but I only started seeing some real gains (L: .5, G: .25 and growing) when I started to do warmups consistently and even during a break in the middle of a long session. Just to be clear, I don't mean preliminary stretches but hot water wraps for a few minutes. I read about this at Thundersplace, in particular that heat loosens up the collagenous tissues and makes it easier to deform the penis into a larger shape. That may not be 100% medically accurate, but it seems to have worked for me. Just be careful not to burn your dick.
