Help.sensitive penis.

Hi, I am new to PE and I’m 18 years old, (pardon my English), when I do jelq or any other stretch technique, my penis can’t help to get a 100% erection, no matter how I adjust my grip, as long as I touched the “head” slightly, it starts to erect, and reaches 100%, I know maintain 60-80% erection for jelqing is good, but how do I do that?

Be thankful you have this “problem”. What are you working toward: length, girth or a combination of both? Although there are other techniques to reduce your erection state, try thinking about something that would cause you to go limp like your grandma walking in on you…naked. Works for me every time.
