The clear winner for us was RedHotPie. This ‘adult dating site for singles and swingers’ is absolutely free and has so many awesome features that we loved, including webcam chatrooms, Amateur Pics by real members, and obviously a real, sexy member base. It also has international appeal, so if you travel (particularly to Australia where their member base is massive) you can get lucky while on holiday. Score! RedHotPie is hands down (and hopefully pants down) our choice of the best of free online swingers sites. Go check it out!
