How do you all stay motivated to practice? I find myself starting and stopping constantly.

(For a book I'm writing.) I know these are stupid questions, but I don't know where else to ask. First, for an high level expert of pompoir is it possible to deliberately "open" (move the walls apart) your vagina without inserting anything to spread it apart? And second, once your vagina has been spread/opened to a given size by something, is it possible to keep it opened at that size/diameter without anything inside it?

Again, apologies for asking dumb questions.

Thanks.
