Brazilian women love to fart during sex if they're comfortable with you. I became quite accustomed to and was turned on by it. Even let a couple fart directly in my face/mouth while eating their ass.
Not my kink... If you have to pass gas, hop up and go to the bathroom. I enjoy the smell of a clean vagina and if it is clean enough, LACK of smell, but the smell of dookie I can do without. I do not mind if one slips out. There is a lot of jarring, but do not just doot up and poot... LOL!
