Sex is about the most intimate thing there is, which means it's just naturally going to be weird and embarrassing. The combination of nudity, hormones firing, and co-mingling of body parts and fluids can really make you lose your inhibitions…and then say or do something in the heat of the moment that absolutely bewilders the other person. A few brave people on Reddit shared their stories of the weirdest things their partners have done in the midst of boning, and it's quite a ride. Warning: in case you haven't figured it out, these stories are very much NSFW.
