Spooning

spooning by ron mueck

Spooning is a sexual position and a cuddling technique. The name derives from the way that two spoons may be positioned side by side, with bowls aligned. In the sexual spoons position, the penetrative partner lies on one side, with knees bent. The receptive partner also lies on the same side, with back pressed against the penetrative partner’s front. Both partners’ upper bodies may be pressed together or separated with just the pelvises connecting, and their legs can also rest on top of each other. The receptive partner may have to lift the upper knee to allow for easier penetration.

This rear-entry position allows for a great deal of physical intimacy, as there is full-body contact which allows for cuddling. However, there is little visual stimulation for either partner, as they are not facing one another and cannot see each other’s bodies fully. Variations on this position include the partners lying on their sides face-to-face or in the ‘scissors’ position. The spoons position may be preferable for couples who have just woken up or are very tired. It may be used if the woman is pregnant, even during the last trimester, because it does not put any pressure on the abdomen.

Kleptothermy

Kleptothermy [klep-toh-thur-mee] is any form of thermoregulation by which an animal shares in the metabolic thermogenesis of another animal. It may or may not be reciprocal, and occurs in both endotherms and ectotherms. Its most common form is huddling. Some species of ectotherms including lizards and snakes increase their effective mass by clustering tightly together. It is also widespread among gregarious endotherms such as bats and birds (such as the mousebird and emperor penguin) where it allows the sharing of body heat (particularly among juveniles).

In at least one case this is not reciprocal, and might be accurately described as heat-stealing. Some male Canadian red sided garter snakes engage in female mimicry by producing fake pheromones after emerging from hibernation. This causes rival males to cover them in a mistaken attempt to mate, and so transfer heat to them. This allows those males that mimic females to become more quickly revitalized after hibernation (which depends upon raising their body temperature), giving them an advantage in their own attempts to mate.
