One helpful resource for married people who are interested in having an affair is the Ashley Madison website. Ashley Madison is a popular online dating site specifically designed for individuals who are currently in committed relationships. As of 2015, this dating services boasts over 42,560,000 members. There has been controversy with this website because it was hacked in July 2015 and private user information was made public.
Another resource that married people can use to find sexual partners is Craigslist personals. Married people can read the posts of people who are looking for causal encounters or dating/romance, determine if they might be a good fit for an affair, and message them to initiate a meet-up. Craigslist also allows users to make their own posting with a description of the type of person they are looking for and what criteria need to be met for a sexual encounter.
Tinder is another popular dating app that married people can utilize. Tinder allows users to search for people nearby, and if both parties are interested in one another, they are able to chat and meet-up. Grindr is a similar geosocial dating app that specifically caters to men who are gay, bisexual or curious and are interested in causal encounters or dating relationships.
