If teens want playboy or whatever then they need to figure out how to get it for themselves. It encourages creativity.
I always talked to my kids about sex, you have to talk about sex in order to talk about CONDOMS, pregnancy prevention, disease prevention.
We caught our son with a playboy when he was maybe 14 or so (he was creative and managed to get the playboy on his own) and we considered it to be a normal part of male puberty.
