I want to chime in, i've had PE my entire life (still do to some extent) and never really last more than 5 minutes. Sometimes i have spasms upon penetration and have to pull out. I believe its due to my increased sensitivity and over arousal. I HAVE however noticed i last considerably longer after doing a jelq routine so that got me thinking about maybe there is a connection there somewhere. I have been doing the death grip daily now for two weeks and had sex for the first time in about a month with a considerably tight woman (which was nice) and i couldn't cum!!! I lasted 20 minutes which is an eternity for me. I DID however notice that i couldn't hold an erection very well though which leads me to believe i did a bit of damage, so i need to find a good balance i think.
I did the death grip routine dry with and without porn for about 20 minutes per session daily if that helps anyone. I might throw in some lube to see how that works too.
