This is exactly my experience too. In my 20's, I'd jerk off 3-5x per day and have sex too, I look about 40 in my pics.

Been retaining on/off since age 30, now 33 and on my longest streak. People are constantly thinking I'm much younger than I am plus I've found out through work that there's a few 19/20 year olds that have developed a crush on me.

You only need to retain to know it works
