"When a woman assumes the posterior position, it may indicate she is the more giving partner or that he needs special nurturing." - psychiatrist Samuel Dunkell.
This classic and comfortable couple cuddling position is great in bed or on a large couch with both laying on sides, forming the little spoon (the person snugged up inside) and the big spoon (the person wrapping outside). The little spoon puts her or his back toward the big spoon's stomach, while the big spoon's top arm wraps around his or her partner's waist.
In this intimate position it is very easy and natural to kiss lightly on the neck, run fingers around the head or lightly rub on thigh or leg for more pleasurable experience. In other words, it gives freedom to do a lot of cuddling in variety of creative ways. Experiment with your partner to find out what works best for you two.
