You may not even be hugging but are so near that your bodies touch in several areas. Cuddling usually occurs when the persons are sitting or lying down. They are very intimate in nature. Women usually start it as an excuse to keep warm. And they always want to do it after sex, which is why men pretend to fall asleep.
