Sex meter: HOT HOT HOT
As one of the most passionate signs in the zodiac, Aries women love to get down and dirty as often as possible. Ruled by fiery Mars, this sign is prone to explosive, passionate romps that leave their partners breathless. The only downside? If they don't get enough (ahem) stimulation, they might seek it out somewhere (or from someone) else.
