Boys can be confused also.
I learned how to “beat my meat” at about twelve. I quickly became an expert.
Then I learned how women got pregnant. This white stuff (cum) was deposited inside a woman. But the confusing thing to me was; I insert my dick into the girl but then what? What makes my cum shoot out?
The only conclusion that made sense to me was, I jack-off until I begin to ejaculate then quickly insert my dick hoping that the majority of my semen would get inside the girl.
Pretty silly huh?
