Why? I am on Bumble and Hinge. Bumble has been my go-to for quite some time mainly because the quality of men I find on Bumble seem (key word: seem) to be more along the lines of what I am looking for and now with the options that Bumble provides i.e. height, religion, reasons for being on the app, etc. No success yet, but I know friends that have had success so ... I'm still keeping the faith.
If you don't have the patience to weed out matches that are explicitly looking for a no strings attached hookup, a quick search on FriendFinder-X will probably make you pretty happy. You can search for potential matches using filters that range from proximity, sexual preferences and even cup size. Too lazy to search? The app has a list of compatible profiles sent to you for your consideration.
