i'm uncut & jelq. i use mineral oil as lube and then just use the foreskin as i would when jerking off. i use 2 different types of jelq: 1. the ok grip 2. keeping the foreskin forward (over the head) use one hand using the ok grip and then before i release start with the other hand (kind of like a milking action.
the other question you had is its a little too much pressure your using. the red dots have happened to me but try just a little less pressure and you should be fine.
Happy Jelqing
