Odd reaction

[Rayquaza]

Sometimes when i think of something really dirty I suddenly find that i NEED TO SNEEZE. What is wrong with me!? Its not that its a sneeze due to an allergy or anything its just i sneeze sometimes when im horny are thinking dirty things. Seriously i need to find out whats going on? Is my body not adjusting to my brain?

[Fact]

No expert on this, but...
Is it possible that the nerves in your nose respond to the fact that other nerve endings are feeling stimulation too?
Just a thought, because of how the central nervous system works, etc.
