Little Rock has a real casual scene; it's just the most discreet one in the country, because in a town this size it has to be. Here's how it actually works, and where people actually find each other. 18+.
Every city this size and this churched runs on the same open secret: the casual scene exists, it's busier than anyone admits on Sunday, and it lives entirely online. The reason is arithmetic, not morality. In a metro of 750,000 where the social core is a few tens of thousands of people, being visibly on the prowl has a cost that big-city daters never pay: everyone you know can see you. So the scene solved it the obvious way. It moved somewhere your coworkers, your gym, and your church group aren't scrolling.
Not the bars, mostly. The River Market strip produces its share of late nights, but bar serendipity in a small market is a slow game, and the discretion problem follows you in the door. The working answer is a purpose-built platform where both people have already said what they're looking for before anyone says hello, and where the pool covers the whole fifty-mile radius: Conway, Benton, Bryant, Cabot, Hot Springs, and every small town in between, which is where a surprising share of the actual demand lives.

Adult FriendFinder is the honest answer. It's been the default casual platform for 25+ years, and it fits this market's exact needs: the pool skews 30s-50s (where central Arkansas's real casual demand lives, a lot of it divorced and uninterested in pretending otherwise), it stays completely separate from the social apps, and the distance sort treats the radius as one market the way locals actually date.
