Need Exercise?

I am convinced that sex counts as exercise for a few reasons: it gets your heart rate up! You sweat. There's a statistic that says you burn 400 calories per hour during passionate intimate relations... and most recently I found out that reaching orgasm actually increases your metabolic rate! So... I don't go to the gym anymore! Why bother with the logistics of getting childcare, driving there, finding parking, paying membership fees, trying not to get eye contact with judgmental people... sure, there are some "logistics" involved in intimacy but they're minimal in comparison.
