I have no real expectations, except that the provider stays the entire time agreed upon (if I or both of us climax before times up). I've only had a few guys up and go after I climax. Most stay and at least talk, some cuddle, some want to go again (because they know I can climax multiple times if properly motivated. LOL).
There has been a small number that after our session was over they want to still talk/cuddle/fool around. Those are usually regulars though. Although occasionally, a new guy will want to do one or all of the 3. One of my newer regulars, the first time we meet (after I came twice), he wanted to stay and go again. Sadly, I couldn't because I had made dinner plans with friends I hadn't seen in awhile. We had already ended our agreed upon time and yet he wanted to stay longer at no additional cost. He has become one of my favorites.
When the times up, I let the provider give indication of should I stay or I go... or if he came to me, should he stay or go.
