After studying in this field for quite some time, it had been brought to my attention that this is quiet common among sixteen year old virgins. I can't ask you this with direct response, because this is a website, but if I could be so bold as to suggest that your abstinence is a result of some desire for the existence of a higher being. Basically, as I have already witnessed, what you know as God has read your mind during those times of illicit thought. We all know that our mind should be pure, in order to make sure of this, God has taken on board your impure thoughts and infected you with a scabies like rash around your 'evil' area. Once you get in contact with your true mind and learn to control your evil thoughts the rash will disappear. I wish you the best of luck on your journey.
Sounds like infected hair follicles
