35 [M4F] NJ/Online - What is your preference on how/where a guy finishes?

I've always wondered (and I'm sure the overall answer just depends on the person) for women, when a guy is about to finish - do you prefer he tells you he's close and asks if he can finish in/on you somewhere? Or do you prefer he just goes for it and finishes where he likes? Is it somewhere in between? Maybe you like to call the shots based on how comfortable you are or what you feel in the moment?

I suppose this question is more of a thing towards a hook up/early-on in a relationship when limits may not be fully known.
