Auriculogenital reflex.
I don’t have a clear explanation for why this happens, but it may help you all to know that there is a strong neurological tie between the ears and sexual response. It’s called auriculogenital reflex, and it explains why there are some women who can purportedly get off from having their ears bitten, etc. There’s also an auriculouterine reflex, which isn’t really well understood either but can be used to help some women induce labor.
(I was a teaching assistant for the guy who taught the section on human sexuality for the sociology department in college. I aced the fucking course, and the labs were amazing.)
Anyway, while it doesn’t fully explain why a guy would lose his hearing after he climaxed, the relationship between sexual stimulation and the nerves of the inner ear canal are well-documented.
Here’s what a real doctor said:
Engel reviewed a group of rare reflexes that are mediated by the vagus nerve, and two of them-the auriculouterine reflex in women and the auriculogenital reflex in men and women-may be pertinent to our case because they suggest the existence of vagal innervation of the human uterus and sex organs. In these reflexes, the vagus nerve forms a bridge between a circumscribed area of the skin, mostly the external auditory meatus, and the uterus and some male and female sex organs. Afferent impulses from female reproductive organs may be conducted via either the vagus nerve or spinal cord. (Engel D: The gastroauricular phenomenon and related vagus reflexes. Arch Psychiatr Nervenkr 1979; 227:271-7.)
