The small Navy Exchange close to my house, sells pornographic magazines only from Hef's empire. Playboy , Playgirl , and Special Editions are readily available behind the counter, sealed in plastic bags, for anyone over 18 to purchase. A friend reported back that their exchange does not sell any porn but Playboy is available in the library on base. Then there is the individual policies on each base and ship. For your private library, if you were found to have a pornographic magazine in your possession you were put on report.
Pornography has a purpose - to get one sexually aroused.
I guess the thinking is if a man on a ship looks at too much porn he'll start harassing the women. In actuality, porn is a deterrent from harassment. If he is given privacy and a magazine then he will have the opportunity to relieve some of that sexual tension which will not be transferred onto female shipmates or prostitutes during port calls. Pattaya Beach, Thailand - a male sailor's candy store of sex and drunkenness. The economy of Pattaya is poor and they rely on the military personnel from around the globe making port calls to their city, which is just outside of Bangkok.
