When it comes to affair dating sites, the best ones are free to join and offer numerous privacy and security features to keep things on the down low.

Popular dating sites and apps, by their very nature, appeal to people who are looking for fun times and meaningful connections, and not everyone in that audience is necessarily totally single. A good number of married individuals have given in to their curiosity and explored their options from the privacy of their smartphones or computers.

Sometimes attached individuals only want to enjoy a flirty conversation and pretend to be single for a bit, and other times they’re serious about starting an extramarital affair. Wherever you fall on that spectrum, the following sites can introduce you to available dates and help you figure out what you want.

Best Overall Free Affair Dating Sites

The online dating world may cater primarily to singles, but they aren’t the only ones looking for connections and hoping to find excitement in their daily lives. A growing number of people have pursued affairs on a dating site or app.

Over 60% of online daters in one survey reported being in a relationship. A separate study on Tinder found that an estimated 40% of its users are already married or have a boyfriend or girlfriend, yet they actively use the app to seek dates.

Many dating apps can work effectively if your primary goal is to meet flirtatious people, set up dates, and explore your romantic options. Cheating isn’t ideal, far from it — but it does happen, and more often than not, it happens on apps like Tinder.

Where Can I Find Someone to Have an Affair?

Online dating is probably the best bet for someone seeking an affair. Unlike the bar scene, dating sites are convenient and accessible 24/7, and they typically don’t have a cover charge for scoping out dates.

Another plus for online daters is that you don’t have to put much effort into covering your tracks and removing evidence of your affair seeking — just delete your account and clear your browser history or remove the app from your phone, and you’re good to go.

Married dating sites can make it even easier to attract hot dates because everyone knows what to expect and what’s at stake.

Affair Dating Sites Offer a Safe Space to View Your Options

It’s natural to feel restless or wonder what’s out there, and an affair can seem like an easy way to escape if you’re stuck in a rut or a bad relationship. Affair dating sites can give you the chance to scratch that itch and meet people who could tempt you to cheat or remind you why you fell in love with your spouse in the first place.

Some people say that a secret jaunt on a dating site helped them gain clarity on what they want, and it actually strengthened their commitment to their marriage. Others found love in someone else’s arms and eventually got divorced.

This journey is about you and what you need to do to find happiness. An affairs dating site or app can lay out some options, and then it’s up to you to decide how far you’re willing to go and what scenarios you can live with. Choose wisely!
