@aidan,
I was thinking and there was something bothering me about buying or giving a young boy this magazine. It was something more than the women's naked bodies - you nailed it (great pun huh) - it objectifies women - you don't want to teach Mo that.
It is natural for him to be curious, but is he mature enough to fully understand why it objectifies women? Granted he will probably see this anyway either through the internet or like others said finding it from a friend's older brother's stash.
But by you or a mom buying for a boy, it almost says that you think it is ok to objectify women - even if you explain otherwise as Thomas suggests - you are supporting financially this objectifying women; ie actions speak louder than words.
If he were to find this otherwise - you explaining it would hold more weight.
