i think you answered your own question. an old rule in life: if it hurts don't do it. if you have found that the redness and odor is directly related to your masturbation ritual then back off a bit.
can over masturbation cause soreness and a odor on left inner thigh of a male. i am a 34 year old male. i noticed if i masturbate to much right next to my penis and balls i will get a red painful irritation with a bad odor. could this be caused by masturbating to much. i noticed if i don't masturbate after a few days the redness pain and odor go away.
