ok this is how i did them last night i grabbed my errect penis at the basewith a tight ok grip then with the other hand i made a very small ok sign palms down grip and put it on top of the head of my penis and pushed down towards the base as hard as i could stand for 3 sets of 30 seconds each keep in mind this is after my 600 wet jelqs. any how i noticed that there was other fluid build up or the worst a thrombosed vein. i just wanted to know if i'm doing these right. i got it from gandoff's video series.
