The best time to have sex is first-thing in the morning. The mind possesses a clumsy handle on reality. Everything on the edges is fuzzy, but the middle is in sharp focus.
After sex first-thing in the morning, the rest of the day can either go two ways. First, it could rock. You had sex first-thing in the morning, a perfect start to the perfect day. On the other hand, the rest of the day could go downhill. You had sex in the morning, what can top that? It all depends on the person, I guess.
For some people, the glass is always half-empty. For others, the glass is always half-full. For an extremely fortunate portion, it is at least half-naked.
