Alright let me give you an honest take — most of what's out there online is useless.
Community size matters more than people think. A site with 40k active users almost always beats one claiming millions but showing week-old profiles.
The mainstream options — Tinder, Bumble, Hinge, OkCupid, Facebook Dating — exist but they're moderated heavily and built around relationships, not adult or casual use.
After getting fed up with mainstream options I ended up on Datelink and it was honestly a much better experience overall.
Happy to share more if you want to go deeper on any of it.
