Been to SA, UAE, and Jordan. Been to multiple North African countries but those aren't technically "middle east"
And yeah why not. Lots of places are cool. It can be a vibe, especially at night. Just note you aren't traveling to Vegas lol, so don't expect that. But if you are looking for haram activities, you can find it. I don't know why you would travel the Arab/Muslim for it though. Also all the apps (bumble, Hinge) work just fine in all the countries. If rolling dolo you can definitely find a local to show you around
