The true test of a passion or "love" is to see what happens after an excessive splurge. A real passion can never reach a true excess such that it lost. Maybe that's why it's called making love, not enjoying love. Every time you go at it, you try to tap an excessive spike of carnal passion. If after the man falls asleep, wakes up, and encounters his groggy-eyed partner semi-awake and cuddling, if then, there is still love, then a "true" love has been made.
