 [ Symptoms ] i have a small dull ache in my left testicle after i masturbated too much i am 18 years of age anyway i masturbated way more than usual during the week it occurred i am not that worried as i have searched for lumps or mass and everything seems ok an answer would be much appreciated [ Disease ] just give it a rest my friend it is not likely that you cause testicular damage from overly masturbating but you can cause enough trauma to have discomfort if your symptoms persist you will need to see your medical provider but i suspect a few days of rest and recuperation will give our over worked boys time to completely recover
