I think it goes it to your intestines because every time i hold a fart for a while i feel abdominal pain and it doesn't go away until i fart. The pain is like a reminder to me saying "its time to fart you held it in for an hour now''
Why is it that when you hold in a fart the pressure goes away after a few seconds? Why doesn't the gas persist until it exits out the anus? Where does it go?
I second this. When I hold in a real motherf*cker of a fart, a total anal warhead, the subsequent abdominal pain can floor me.
