give it a rest my friend. the penis is like any other part of the body. it can become bruised (inside) and become sore with use. if you rubbed one of your fingers like that on a regular basis i suspect you could get a sore finger! as you know i cannot examine your sore penis over the internet so if your symptoms persist you will need to have a visit with a medical provider hopefully an understanding (male) provider who can provide you with some confidential advice. because your penis is sore limit your masturbation a bit until your symptoms improve. you can still achieve self-pleasure by being a bit more gentle with your tender part. you might want to look into using a penis health creme my friend. these cremes are made just for guys who masturbate a lot and it will help with soreness chafing and rough or dry skin. easy to use and totally safe too. you should check it out.
im 15. after i masturbate my penis hurts and feels sore when i get an erection after. im a virgin and tightly cicumcised
