12745327, Penis in Vagina. Everything else is a form of masturbation. Posted by Boogie Stimuli, Mon Mar-09-15 09:52 AM
A hand job is a penis/vagina being masturbated by a hand. Oral sex is a penis/vagina being masturbated by a mouth. Anal sex is a penis being masturbated by an anus.
It's interesting that the word "sex" also denotes male or female in the biological sense. There's only one act that creates those beings. If the parts used in the act, don't have the purpose of reproduction in that species, it's masturbation.
