Not possible to jelq
I wanted to try jelqing, but it is impossible because my penis gets fully erect after a short time (like 60 seconds). The only solution I can think of is to masturbate first, wait a few minutes and then start jelqing. What are you guys saying?
PS: I think my penis is rather sensitive because I could easily cum 5 times a day and probably get hard erections with 10 min intervals after cumming.
