As a long time online dater who is always on the look out for a bit of slap and tickle ive gotta say that socialsex is definitely in my top three go to sites for casual sex/ NSA/ hook ups what ever you want to call it. Its hard to choose between this, tinder and my current fave flirtydater.com. All are very different, some are better for mobile, some are better for chats, some are better in cities, etc but they all get results if you use them right and thats whats important at the end of the day.
