I used to masterbate with soap. It was fine, I didn’t know what lube was yet and moisturiser was for women and gays. I thought for the longest time, that as you grow up, your penis loses its skin, similar to a snake, it sheds its skin and grows into a larger, fresher skin. So every time my penis was losing its skin I was excited, in pain, but excited that I would be having a larger penis soon.
As time went on this happened more and more frequently, every few days sometimes. I thought, wow! This is a big penis. Turns out, the soap I was using was dehydrating my skin, and killing my skin, likely it was seeping into the skin, the chemicals inside of the soap weren’t good for it too. Also, it’s liquid soap that has seeped into the skin, you need a nice wash to get rid of that. I didn’t know that. It’s probably why my penis looks nothing like I imagined it would.
