If I were to catch my fifteen year old son watching hentai, I would tell him only to fap behind a closed door. After all, if he's going at it in the restroom (if it happend to be the only restroom in the whole place), then that would be an inconvenience. Furthermore, I would be mad if his habit became intrusive. For ex, if he's got bad grades. Pacifying porn addiction is the reason sickos exist? Kinda. I mean, porn is made for you to either masturbate to or for couples to watch while they're going at it. But if there is no porn and prostitution is illegal, what options does a single guy have when he's tired of using his imagination? I mean, the kind of single guy who would either be too busy or unwilling to get into a relationship just to flock. It's not like one-night-stands happen all of the time either. I am definitely not saying that I condone the acts of sickos, but I think there would be a drop in sex crimes if prostitution was legalized here in the U.S (while statutory rape laws are intact). (Hell, I would love to go down to a nearby brothel and get some action myself right now, but there aren't any because prostitution is illegal. I think I would definitely get rid of my porn if I were able to pay for sex too.) For instance, many street hookers are abused and raped, but reports are not filed because they would immediately be arrested for soliciting sex. If it is legalized, they would be able to work in an institutionalized environment and they would have police protection like other females professions (and they'd be clean). Sounds like Maslow's Hierarchy of Needs applied to a whole society to lessen sex crimes.
