When I was in my early '30s I began jelqing with lubrication and using a Joel Kaplan vacuum tube. I would do 100 each day when jelqing and take off one day a week. I would pump for around 15 minutes and worked up to 30 minutes. I only knew of one way to perform the jelq and I had great results in a little under a year. Measured right at 6" when I began and eventually had an honest 7 1/4", 7 1/2" on a really hot sexual session. Thickness didn't change. My wife was amazed and I didn't reveal what I was doing until she commented, "Man, your dick is hitting spots that've never been touched inside me." And she could no longer "deepthroat" me. It works with time.
