thats just a sick question.go ask a doctor.this was a very disturbing question...GROSS!!!!!
The food you eat is decomposed in your gut. As with any decomposing item it forms gas. When it escapes your body this is a fart and the smell depends on what you ate earlier.
Any substance on your rear end is unlikely to make the smell stronger.
The bad smell is due to bacteria present in your gut. Indigestion is the main cause this causes a lot of gases. Add bacteria to it and you get bad smells.
The odor of farts comes from small amounts of hydrogen sulfide gas and skatole in the mixture. These compounds contain sulfur. The more sulfur-rich your diet, the more sulfides and skatole will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts.
"The gas released during a flatus event frequently has a foul odor which mainly results from low molecular weight fatty acids such as butyric acid (rancid butter smell) and reduced sulfur compounds such as hydrogen sulfide (rotten egg smell) and carbonyl sulfide that are the result of protein breakdown. The incidence of odoriferous compounds in flatus increases from herbivores, such as cattle, through omnivores to carnivorous species, such as cats or dogs. Flatulence odor can also be caused by the presence of large numbers of microflora bacteria and/or the presence of feces in the rectum."
