Scorpio (Oct. 23-Nov. 21)
Known as the sex sign of the zodiac, Scorpios are ruled by their reproductive organs, so yeah, it's safe to say they're at No. 1. "That doesn't mean they'll get in bed with just anyone, though," Dossé-Via said. "Scorpios are often super selective and have high standards, so you'll have to match their sexual and emotional intensity to be deemed as worthy."
