Sloths are the slowest mammals on the planet. But if there's one thing they're quick at, it's sex. Seriously, it takes them 5 seconds, including foreplay, to get off. So, next time you're a one-pump-chump and hear, "That was the quickest orgasm on the planet," inform your partner otherwise. And, hey..., it can be quick and sexy, just like the quick and sexy sloth.
