Sodomy: anal or oral copulation with a member of the same or opposite sex
And, yes, that is the official definition.
And, yes, that is the official definition.
Oh, well if that's the definition of sodomy, then yes, it's perfectly fine, because oral sex is a large part of the tantra of Shir ha-Shirim.
Of course, people could always adjust their definitions when they find out more information from this very, very, very small book with so much packed inside. I doubt they will, but that's not to say they shouldn't.
Blessings.
