Although it isn't a new cosmetic surgery, so-called "vaginal rejuvenation" has become on of the most highly publicized procedures that more women are seeking out these days. The combination labiaplasty and vaginoplasty is meant to tighten genital muscles and diminish the appearance of the vulva, literally leaving less to look at -- as in the opposite of a breast augmentation.

237 Reasons Humans Have Sex

Asking why humans have sex might seem like an obvious question. It feels good. It bonds us together. Oh, and the future of the human species depends on it. But prior to the 2007 study, "Why Humans Have Sex," published in the Archives of Sexual Behavior, "the most comprehensive existing taxonomy" cited only eight reasons: "to feel valued by a partner, expressing value for a partner, obtaining relief from stress, nurturing one another, enhancing feelings of personal power, experiencing a partner's power, experiencing pleasure and procreating."
