The Examiner explains why cuddling their partners is so important to women.  Essentially, cuddling is a survival need for women.  Women need to establish an emotional bond with whoever they are having sex with, otherwise they are in danger of being left carrying any resulting baby.  Cuddling raises oxytocin in women and makes them feel good because it is a signal that that emotional bond and commitment has been achieved.

A 2006 study by the Berman Center for Women’s Health in Chicago showed that couples who regularly indulge in spontaneous, non-sexual physical affection are more satisfied with their relationships.  So cuddle if you would like your woman to feel closely connected and peaceful with you. You will see the benefits in terms of increased sexual satisfaction as she appreciates you more for understanding her cuddling needs.
