Length gains but girth loss?
So I have started my PE journey a week ago. My routine for the first week was 100 jelqs twice a day, both done in while showering. 5 min warmup and 5 min warm down in the shower, in between I do 100 jelqs with soap so its 200 a day. I also do manual stretches whenever I can. As a result, to my surprise, I gained almost .5inch in length(around1cm). But my girth went down. I don’t usually measure girth. I just measure the width of my penis. It went down from 4cm to 3.9cm, I don’t know if its because the error while measuring or I am doing something wrong. One thing I am sure that width hasn’t gained a bit. Please help!
