I couldn’t tell ya, but I guess laziness? They want an entertaining room but they want everyone else to do the work to make it that way? I dunno. I don’t get it either.
“Crazy” comes in many flavors of course, but in general, if it’s spoiling the mood during my visits, it’ll eventually feel like a chore to keep visiting, and I’ll stop.
In the examples you gave, emotional is fine as long as there’s no unnecessary lashing out at people that don’t deserve the heat. But everyone has their moments, so it’s totally understandable once in a while.
Demanding - depends how persistent they are and how unreasonable the demands are. Demanding tips for performances is completely fine, for example. But demanding a guy take you private (has happened to me), or demanding they show up every night on schedule, stuff like that is out of bounds. And again, anything that spoils the fun will remove my incentive to return again.
“Unstable” is the example you gave that would chase me away the fastest, because there could be an element of actual danger involved.
For me it depends on the model. The ones that have had me as a longtime regular are a combination of both. But I visit some models specifically for transactional “sexual stuff” with little conversation, and also one or two models that I rarely tip for sexy stuff but I continue visiting and tipping “just because,” because I enjoy their personalities (and by extension, I enjoy the vibes of their rooms, even on nights when I could care less about seeing anything explicit).
Not necessarily a conversation, although that is a great selling point. I just want the interaction to be pleasant. In other words, it’s fine if a model and I have awkward verbal/written chemistry as long as we’re both pleasant and kind about it. A good attitude makes up for a lot.
But as always, that’s just my opinion, and there’s always a chance I’m an outlier.
