I see nothing wrong with the current CONSENTING ADULTS standard. But as this thread is about Santorum, how about Santorum's downright laughable view.
"As I would with acts of other, what I would consider to be, acts outside of traditional heterosexual relationships. And that includes a variety of different acts, not just homosexual."
And to be clear he's talking about things, he believes should be outlawed. With his history of what he considers 'traditional' in heterosexual relationships, that means only procreative sex.
So are you for laws against oral sex Robert? How about manual sex? Masturbation? Regulations on positions?
