—The X-rated is a sex position in which the giver lies on their back and the receiver straddles them facing toward their partner's feet. After being penetrated, the receiver stretches their legs back and leans forward, so their torso rests between the giver's legs. The X-rated gets its name from the "X" that the couple's legs form when this position is executed properly. Plus, it's so hot, it should be X-rated!
