Why does my breath smell like onions after I suck my girlfriends nipples?

It happens every time not just sometimes, but when ever I suck my girls nipples my breath smells like onions, and im REALLY curious on why.

Women's breasts have quite a number of sweat glands in them. Now women's sweat has an onion-y smell to it because female sweat contains more sulfur-contained compound which, when mixed with bacteria on the surface of the skin, creates thiol. Thiol is what makes it smell like onions.

So when you suck on your girls nipples you're really sucking on some thiol which makes your breath smell like onions.

In retrospect I wasn't sure if this was a serious question but I decided to answer it anyways.

maybe u had onions in ur dinner or somethin u eat bt didn't no ??? :)

a womens nipples have many sweat glands nd it is especially a que point if she eats onions because you do sweat the fumes out , (: not all womens nipples are like that tho
