Hi there loyal,
More complicated being uncut huh:) . Well, If I do wet jelq I don’t pull the skin back, although I think this would also make the foreskin to be longer, guess its OK if the result is also come with some length gain. Nowadays I do dry jelqing more often as I don’t need lube-the benefit of being uncut, and I know from what point on my shaft I should start jelqing so the skin will act like the lube. You should try it, find the best spot on your shaft so you could jelq your entire shaft using the skin in one stroke.
Keep jelqing, have a nice day:)
Regards
Occa
