Question for Gainers

Hi everybody, I am currently about average in length but have a good girth, so i am trying to focus solely on length. I've read about the benefits of warm ups and cool downs, but i seem to be doing fine without it. I am looking for a pure length routine that doesn't take more than 20 minutes. I also want to know if do jelqs at low erection levels, will it help make more gains in length than in girth. If it does help to have a low erection level should it be at completely flaccid or like 30% to 50% erect? I am also thinking about adding an edging session on the 2nd day of my 2 day on, 1 day off routine. Do you think this will help with my length routine, and does it help you last that much longer when you have sex? Another question about edging, how many time should i reach the point of no return, and should i kegel in between points of no return? How long after a edging session do i have to wait to ejaculate, but i want to wait long enough that i get everything out of the edging session? Should i edge right after my PE session or take a break and do it before bed?Oh my gosh, I'm sorry i am taking up so much space and i promise i won't reply again until someone else says something. I read Kingpole's edging 101(very thorough post that i feel like I'm blessed to be reading it, I love when the veterans give detailed explanations of easy tasks.) Kingpole said that eventually you will reach a dry orgasm which is very spiritual. I don't understand this exactly. Do you lose the ability to ejaculate with sperm, and I masturbate often, will this keep me unleashing sperm. I am basically worried that if have dry orgasms, i won't be able to cum when i'm with a woman. Thanks and sorry for the long post, I'm very eager to see the replies!!
