Teen hyper-sexuality but im a virgin

Patient: Im a 16 year old male and have always been horney when i was a kid i would play with myself all the time. Now i wake up every morning with an erection i have multiple erections per day and cant fall asleep with out masturbating. this has been going on for a long time it seems like i have barely started puberty i still have a small penis and barely any hair and no facial hair. im not sexually active and i have overcome my addiction to porn. Is there any medical reason for my hyper-sexuality
