I don’t get the 10 x sneeze = orgasm thing - it makes no sense at all. A sneeze can be mildly pleasant. A second one is usually at least slightly less pleasant, and so on.
When I sneeze it is most often quite a few times consecutively. I find it quite pleasant as long as I can just stop everything I am doing. Obviously not good when driving or operating heavy machinery.
I have also started sometimes getting a case of the sneezes after orgasm. I have no idea how this started.
Well, OBVIOUSLY, you’re doing them in the wrong order!
From what I am aware of, sneezing is common with sexual activities due to the mucous membranes inside getting inflamed with blood, thus making your nerves more tickleable or the inflammation itself causing nerve tickling, which makes for sneezing.
