I sometimes cover my erect penis with a tube sock after I masturbate in order to help keep some of my lingering sperm from slowly trickling onto my body.
P.S. - A banana was used in place of my "manhood" though I like to think I'm a lot longer and wider than the above picture!
P.S. to the P.S. - OK, OK...Maybe I'm exaggerating a little bit...Or maybe not?
