I have been on opiate meds for years for chronic pain. Opiates are known to cause testosterone levels to decrease.I am on testosterone replacement using a compounded T cream. I was directed to apply the T cream to the head of my penis to regain feeling . I am back to my normal self. I reccomend having your Test. level checked. Tcream can help regain feeling in your penis. DO NOT GEL on your penis; it will burn(alcohol)View Thread
