Is celibacy time different from sex time? I'm talking perception, of course.
From romance to foreplay to intercourse to afterglow (hopefully), time can pass in an instant. But if the sex is a bore or a chore, you're looking at the little clock on the bedside table while he's pumping away, thinking, "Geez, just come already."
If you're single, you may be thinking, "Will this time in my life ever be over?" You measure time between dates or phone calls from him. You look at the calendar in shock, realizing it's been X weeks/months/years (yikes!) since you last did the wild thang.
Time is relative, but one thing's for sure: the more joy, whether you're having sex or celibacy, the less time feels like watching a pot boil.
