Get with your doctor: You're almost a man and it's great that you've kept yourself for somebody truly special. I hope nobody's caused you to be conflicted about what you do when you're alone. I also trust you're getting stimulation from being around / seeing possible partners. Two entities that your physician might consider in working you up are hemochromatosis and prolactinoma.
