Nope, you can definitely squirt without orgasming, however the two often come together so it takes some practise. It’s mostly deciding to let go much more deliberately than when you actually squirt when cumming at the same time. So yes, when you feel that unique need to pee that comes from g-spot stimulation you have to decide to push it out, knowing it’s not pee, it’s ejaculate.
So no, no punishment. But just like male denial sluts need to clean up the mess they make when they are ruined, you need to lick up the mess afterwards.
