Hello, I am 18 and this is an embarassing question for me to ask but it is driving me crazy to know the answer.
I masterbate everyday. I use my hand by stroking my penis like most men do. I always use the same method and it is always in the same place. I have noticed recently that the front of my penis is getting flatter and more curved. Could that be caused by masterbation? My penis is thick, can masterbating too hard or too much make it narrower?
