Funny you should mention that on a homo "marriage" thread.
That's the same thing the NAMBLA members said about their boy toys.
Apparently this is a valid, though discouraged, choice as long as it is safe, legal and rare.
Well, maybe the words, "another who can freely consent" implied reaching an age of majority (or a lesser age, if there is parental consent, just like with heterosexual marriage) to me, and not to you. Michael Jackson's playthings did not freely consent to anything, because they were incapable.
There isn't a place in hell hot enough for a child molester, in my opinion. But I have to acknowledge that at a certain age (which may be debatable), a person can take responsibility for their own life.
