Thank God, cause I imagine putting that back on is a BITCH!

Besides, I never believed it could really get that much better than it already feels during the "happy moment". Hell, much more and I would probably be passing out during it:) Which no one wants. That last thing your girl wants when you hit the big O is for you to head butt her (picture scene from Superbad where Seth passes out into Jules head) ;)

Although that would get me out of cuddling...
