My take on that Meatloaf song...

So, just what is "IT" that he wouldn't do for love? Looked up the lyrics, and the meaning of the song seems to me to be this: he's a hopeless romantic who pledges his undying love and devotion, and promises to never leave or betray ("but I won't do that"), despite the fact he'd "do anything for love". She, realizing he's a hopeless romantic, believes the moment he perceives he loves another (and him being a hopeless romantic, it's inevitable that he will), realizes he will leave and/or betray, due to the bitter irony he WILL in fact "do anything for love". She skewers him with his own logic, a concept he cannot grasp. Then again, maybe that's too complicated. A wise man once said "the simplest answer is often the truest." So by that theorem, maybe it is about butt sex.
