Men fart in bed because they generally produce more gaseous product in a day than women (based on body mass and stomach/intestine size) and tend to release this gas when they are most relaxed. This happens to be when they are laying down in a relaxed and comfortable environment.

Women may feel that fluctuating while in bed is a disgusting habit, but generally a male produces more gas than women in any given day. Usually a male can pass gas when going to the toilet or releasing the build up while walking around, but it is when his body is stretched out and in a relaxed position when the most of the gas will be released.

So ladies try not to be too harsh on your male partner when next you are both lying in bed hand he tries to tear the sheets in half with his bowel movements. Just remember his stomach is like a big gas factory, trying to break down beautiful food that you have cooked for him. This is the same food that gives him the nourishment and energy necessary to tackle a hard day at work, so he can bring home his paycheck and buy all the pretty shiny things that he likes to shower you with and show his affections to you.

So in summary, when your husband or boyfriend farts in bed he is really showing you his affection!

Your man might have been doubling over in pain trying to keep the gas from releasing and to get up to go to the toilet would have been delaying the inevitable. His ass opera might have woken the whole house up if he played the toilet bowl like a ceramic tuba. The curvature of the toilet bowl has the best acoustic resonance to reverberate an amplified sound wave throughout your neighborhood. His end of day overture is probably going to sound like a 12 second fart changing tones 3 to 4 times.

Okay, okay, call him a lazy so and so, then send him off to the couch. But after you have calmed down keep your ears peeled because you will most likely hear him farting on the couch, trying to rip the backrest off with his wind, while he is lying down.
