Group sex involves three or more people, but usually isn't centered around an established couple, as a threesome is. Group sex might originate during a night at a swingers' club, or at a sex club. Sometimes people also seek each other out online. There are more and more sites that make this possible, and it often has the advantage of avoiding the complications of jealousy or the risks of unstable couple relationships. Group sex can also be part of outdoor, dogging (British English) or adult movie theater activities. The underlying pleasure comes from emotional detachment, and the thrill of getting to know strangers in such an intensely stimulating setting. Although group sex has been a source of mass fun since ancient times, it has its modern caveats. Safer sex is an absolute must in these contexts, and consent should be in constant negotiation through communication between partners, strangers or not.

We always think of the middle aged man in the brand new Porsche as the one looking for a partner who is younger than him. We picture Hugh Hefner or, god forbid, Woody Allen. But actually, nowadays women are breathing new life into the age difference dynamic. More and more, women like Madonna or Demi Moore are taking partners who are ten or more years younger than them. We've even named these hot and resourceful women after the intimidating predator, the cougar. These are women who have been around the block a few times and are now taking charge of their love life with a younger man. Of course, this still isn't as widely accepted as Hefner's antics, but it's definitely a sign of the changing times.
