Don't tell me what I can and can't use for porn.

Directly below the vagina is the urethra, similar to that of the male’s penis, but flush with the skin and only used to expel urine. The vagina and urethra do not intersect, though they end at the same patch of skin.

Worth noting is that the urethra is not much larger in a woman than in a man, and lacks a vulva. If she says “wrong hole”, she means it.
