Blood flow and gains
Every time I ejaculate, my penis turns to it’s flaccid size in a minute. The same happens after a jelq session, it doesn’t stand hard and big for too much time. My friend told me that after having sex, his penis stands hard and fat for some minutes. His penis is big (around 7.5x5.5) and he grew a lot doing jelq (2” length) the last two years. He’s 20, it could be natural, but we don’t know.
The question is: Does your penis stay full of blood for a long time after ejaculation/jelq? The second is, did you have good gains when comparing to the average?
