I'm 14 and know how to do it. I usually use lotion or soap if im in the shower. i have some hairs around my penis and some under my arms.. i get to a certain point, which i thing is an orgasm, where everything feels good for a few seconds and then my penis tickles when i touch it..
Any advice helps
Sounds like you are having a dry orgasm (otherwise called shooting blanks), but you are not yet far enough through puberty to ejaculate semen. Once your body is further through puberty you will begin to ejaculate semen when you reach the same point in the future. In the meantime, enjoy the pleasure of masturbation without the need to clean up a wet sticky mess.
