My husband has been having a strange sensation of coldness on only the tip of his penis when he sits for long periods of time at his desk or when driving. No pain, no problem with erection, no urination problem He is 48 and had a minor heart issue a year ago. He is on medication for his heart, but has slowly been coming off of certain meds, blood pressure and effient for his stent have been taken out of his regimen. He said it is the same feeling he had when riding a bicycle.
