This Valentine's Day, while you couples and triads have romantic meals and cover your furniture in rose petals or whatever, the singles of the world will be firing up Netflix and a bottle of wine, and then, inevitably, glancing down at their hands, or the drawer they keep their vibrators in. Just you and me, buddy. Like always. Masturbation is great, obviously, but like any indulgence, too much of it can be a bad thing.
