Why is masturbation considered "taboo"? It's perfectly normal. I think that both boys and girls should be allowed to masturbate in public washrooms (especially at schools). Boys can masturbate standing up into a toilet or urinal, and girls can masturbate while sitting on a toilet. Semen and "girl cum" are both natural products of the human body, like urine or feces, and feeling horny is just as normal as needing to go pee or poop.
