Why do women hold in farts?

Answer 1

They don't hold them in.

Out of politeness, both men and women avoid expelling gas while in the company of other people.
Expelling gas, or farting, is one of the ways your body gets rid of unnecessary gasses and toxins inside your body. If you held in all the gas in your body then your digestive system will expand to stretching point, which will be painful. If the gas still isn't expelled, then your body will simply explode from the inside-out. It takes a lot of gas to do that however.

One of the gasses inside you is methane, which is flammable. So if you have huge amounts of gas inside you which you're not letting out, you're technically flammable.

Aside from that, it is physically impossible to hold your gas or farts in forever. Your body will simply expel the gas while you are asleep when you can't control it.

Answer 2

Girls are self-conscious and believe that they should create a perfect image for boys to see in order to find a future mate. It is also hard-wired into these girls' brains through conditioning from their parents that farting is bad and uncivil.

Answer 3

Because they dont want to draw attention to there anus where most men like to stick there penis's.
