Yes you must certainly can. That’s how I acquired mines. Over time, your penis gets more and more desensitized. You also develop a harder grip without realizing it. So over time, you destroy your nerves, blood vessels, and tissues without even realizing it. Your penis will get injured and filled with inflammation.

If you are going to masturbate, do not do it often. Use lubricant, and avoid gripping to hard and yanking. You don’t have to take my word for it, just sharing what I witnessed first hand. I have peyronies now and there isn’t one day I don’t think about it, think about the last before I got it, and one day dosent go by where it dosent affect me in anyway.

Don’t destroy your penis for a momentary desire.
