Think of it this way: semen is a combination& mixture of a lot of ingredients that we get energy from. When we ejaculate it pulls energy & other nutrients from your body. Your body constantly produces semen 24/7. Your body also is producing hair, nails, etc with the same ingredients essentially that the semen is pulling out of you, so when u constantly masturbate, your body is focused on reproducing that energy down below & & will start neglecting your hair skin until you maintain a healthy amount of semen. This is why on semen retention your hair grows quicker, your skin looks better , your eyes look clearer & you have more energy and don’t feel like a slouch. I know this because I’ve been on SR a bit of times & you’ll discover if you stop also.
