Why it’s hot: “An enormous part of the sensory nerves in the brain are devoted to the skin on your feet, but many people don’t focus on them,” says Fisher. “If a man wants to put a nice clean foot in his mouth, it will stimulate a very strong physiological response throughout a woman’s body, because part of the sensory cortex is stimulated.”
How to activate them: If you want to work your way up to toe sucking, start by gently pinching her toes. This will relax her and build sexual anticipation. When you’re ready for the big time, you’ll get a great payoff: “Sucking her toes can be as pleasurable to her as oral sex,” says Laurie Watson, certified sex therapist and instructor at Duke University and the University of North Carolina Chapel Hill medical schools.
