If you want to keep your affair secret AdultsFun.club is a better option. It's safer because it's not so well-known and they control their platform: they ban dodgy users so scammers don't run rampant there like they do on AshleyMadison. AshleyMadison is full of scammers and it's very unsafe. You can have people stalking you, requesting money, exposing your correspondence, ruining your reputation. I learned my fair share of lessons: I was blackmailed and this scammer nearly ruined my family.
If you want an affair - AshleyMadison is the wrong place. It's a money scam!
AM managers are greedy. I think they are up to their necks in this scam, otherwise I don't know why they never ban profiles of blackmailers and money hungry scammers. All my reports were ignored. All scammers are still there "working" with their new victims preying on their money.
