This can be due to psychological reasons for use of marijuana. Otherwise it can be due to an allergic reaction (say to body lotions, condoms, soaps etc) or it can be a skin condition like eczema, dermatitis etc or it can be a fungal infection. The other reasons are peripheral artery disease (by dopplar ultrasound) and a peripheral nerve disease maybe due to diabetes.
Please discuss these possibilities with your urologist and try stopping marijuana abuse.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
