i m 19yrs old and hv been masturbating since 13 daily 2-3 times at least......recently i read an article about over-masturation and its effects.the effects are pain in groin or testicles,lower back,fatigue,hair loss,anxiety,fuzzy vision.and i've experienced pain in grion,lower back and hair loss.i play a lot of football which might explain the pain in groin and hair loss is due to i think heredity but there's no explanation for lower back pain.....
