Men, please take note — pillow talk after a passionate night matters a lot to the ladies. In fact, it’s as important as sex for a healthy relationship, says a study. Researchers at the University of Michigan have carried out the study and found that women whose partners nod off after being intimate, are left feeling insecure and wanting attention.

The study has found that cuddling and talking after sex is a crucial way for a couple to express their commitment to each other, Daily Mail newspaper reported.

The researchers have based their findings on an analysis of 456 people who were surveyed. Lead researcher Dr Daniel Kruger said that the study of couples’ sleeping patterns found men often fell asleep first. Kruger said: “When their partner feel asleep first, they craved that bonding time, for expressions of affection and endearment, and felt it was lacking. “A woman could be pregnant. Although with contraception that may not be the case anymore, we still have this psychology, and the post-coital time is when the couple makes promises to each other.The time couples spend together after sex might be as important as what happens before it in terms of building the relationship, yet it’s rarely been studied.”
