FORGET keys in a salad bowl, Silicon Valley swingers are using hi-tech apps and websites to swap sex partners.
Entrepreneur Ben Fuller has created modern technology to lure wealthy San Francisco professionals to “lifestyle parties” where couples mingle, dance and even have sex.
Mr Fuller started throwing the Bronze Party in 2011, in which more than 1300 registered members use apps such as Secret and Auto Date to RSVP and see who is attending.
