Let me state, to begin with, that my wife is a great, passionate and tender kisser. She can singe the tips of my crooked toes with one of her smoldering lip locks.
Let me also state that, at the time, I was working a very odd graveyard shift -- every other night, which just wrecks you.
I'd also like to enter in to the official record that I was very relaxed -- a state I also attribute to my wife (then girlfriend).
I would like to point out that this only happened once.
AND Indiana Jones did it in Raiders of the Lost Ark.
While my wife (then girlfriend) was kissing me (tenderly, passionately, smolderingly):
I fell asleep.
And I will NEVER live it down.
