I was also disappointed in the notifications, which I found too pushy. CMB was constantly "gently" reminding me to message users I'd matched with. I eventually disabled the app after receiving the following notification: "Show [match name] who's boss and break the ice today!" Should a potential future relationship be rooted in a hierarchical power dynamic? At the end of the day, I have friends who've had good matches on CMB, but it isn't my favorite app.
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.
