>Is it true?
the anus is a sphincter muscle that is tonically contracted preventing ingress of water
the vaginal opening is not a sphincter , so isn't as difficult for water to penetrate. similar to how air can enter and be expelled (a "queef"), it's certainly possible for ~some~ water to enter the vaginal canal. however it doesn't "fill" with water due to surrounding musculature except in extreme cases like putting your gaping cunt under a pressurized steam of water like in the video you quoted.
