ok.. first of all im an asian and im 22. my erect penis is 4.5' and im uncut. and i just want to start jelqing to increase both length and girth. but when i start to jelq, my foreskin tend to move along with each of my stroke. every yime i want to retract my skin, i have to release the grip and this will make the blood flow back to the base. so, basically i cant push the blood up the head consistently and it really troublesome especially with my length. is there any suggestion to help?
