This question depends on how you define success. Before writing to someone, you can check what type of guys he is into. I am hoping and praying that this becomes the next Tinder. I'm in the United States, and most of my matches were from Europe — which is fine if you're just looking to bitch about the same thing together, but not awesome if you're trying to start a legitimate relationship.
If you're a single man and you're continuously striking out on Tinder, you should really consider leveling up to the gold standard in online dating.
Most dating sites will match people on the traditional personality traits and interests — and having the same values and hobbies as your SO is obviously important. If it's some quick action you're looking for, or if you're just looking to connect online with people in the same mindset as you so you can get off, AdultFriendFinder is the place to be.
The ads with same-sex couples are an obvious giveaway, but OkCupid has snuck in other little features to weed out more conservative-minded people.
