What sites do you know for non-standard relationships? Let's say for swingers or for three lovers. We want to try something new and get a new experience. If there are such proven platforms, then share.
My friend also once wanted to try relationships with swingers and was looking for a platform for such acquaintances on the Internet. He tried several sites, but nothing worked. Then he was recommended best dating sites for lesbians. Here he found a reliable platform for such acquaintances. Now he and his wife periodically meet on it for a party swinger.
