AdultFriendFinder is kind of the first site that comes to mind when I think of finding sex online. It’s perhaps not a regular dating site, that’s for sure, but it’s not marketed specifically as an affair site either. The reason it has my vote as the best site online for affair dating is because they have more members than any other sex site out there (several different people to meet up with!), their site is super safe and discreet (an excellent option for staying they a secret from your partner!), and everyone I’ve met on AdultFriendFinder is super open-minded and down for anything (not seeking a love, you should never extremely proper care if you are searching to cheat!).
