The most obvious result of sleeping au natural is the effect it has on your sleeping partner. Leaving your clothes at the door can lead to increased intimacy, more cuddles, and more sex. If you are in the dating stage of your relationship, this is your chance to blow someone away. There is nothing sexier than a partner that is confident in their skin. For committed relationships, increased skin-to-skin contact with your partner increases the release of oxytocin, the super important bonding chemical!
