I'm not much of a jelqer, but when i've done it in the past especially with the skin over the glans it would swell up with the reps. End result, foreskin growth, fleshy and a better color. Since I've moved on to pumping the same thing happens, but even more growth.
Man, my foreskin is almost non-existent, but I've noticed that when I'm flaccid SOMETIMES it curls up around my glans a lil. Once I get a job later this month I am saving up for the TLC tugger or some shit like that...there are these cones they sell that have a pretty good public view. My friends, we are here to create an army of perfect dicks (in our own individual eyes) and bring hope, knowledge, community, brotherhood, and pride to the insecure! Do whatever it takes to make your dick the best it can be. People do it with their bodies, with general fitness, and non-steroid bodybuilding, and we can do this with our dicks too, and make us all look great naked!!!
For the past few months I have been trying to add extra skin around my glans. In the past I used plenty of lube and kept it moist. Now I use lube and water to start, but I only add more water when it get too difficult to jelq. I am pushing up a lot of skin around my glans. When I do my UV's now and the skin starts to bundle up I incorporate a stretching pull after finishing my jelq stroke. The skin acts as a barrier between my fingers and my glans. Also, the more friction there is the easier it is to maintain extra slow jelqs since you aren't gliding up your shaft as easily. I find it neat to be able to sculptor and change the way my unit looks. My goal is that when my wife is stroking me she can push skin up and over my entire glans. The skin riding over the edge of my glans is a different feel than when the skin didn't do that.
