The first time. For some it's uneventful, anti-climactic (pun intended), and unmemorable. I'm glad that wasn't my experience. I waited.
But once I got a taste, it was like a potato chip. One just isn't enough. I became insatiable. And as the years have passed, that desire has waned, but every once in awhile, on a Thursday, it comes back, hot and forceful.
