when you really really wanna cum, but there is just no Man around to give your permission.
It really can tough and even frustrating sometimes but selfish pleasures is never the answer. We just cannot ignore the fact that male consent matters. Men deserve this kind of respect. We just cannot go around and cumming all day, that's no way to be a girl. So know that it is perfectly fine to masturbate and edge as much as you want, and more importantly where you want, but you cannot go around cumming whenever you feel like it.
Sex (and that includes female masturbation) is about male pleasure. We want to be good for them, we want them to like us. So masturbating keeps us horny and also it stops us from having dry pussies. Because when a Man wants to enjoy you and you have a dry pussy, that can be considered rude. Masturbating and especially edging schedules can really help you with that.
Pro Tip: Edging right before you fall asleep guarantees nicer dreams.
So when you need to cum, need it so bad. You gotta find a Man to give you his consent. When you are in a relationship, it's easy. Ask your Man. When you are single it can be a bit more tough, but luckily there are many Men on the internet and if you are nice, pleasant, and submissive they will eventually grant you permission. So don't worry, you will get permission sooner or later, as long as you are a good girl and don't do selfish things.
