I’d worry a little nip it about somebody who never farts. Freud had a name fir that. But if one is just having an out-of-control bout of it, she should excuse herself without her partner requesting. Re-schedule, or just agree to part as friends. I know this gets complicated if there is a professional fee, or a room rental, but both are human, find a solution.
@mickcuddle Ladies do not fart. In the words of Iris DeMent—I will let the mystery be.
I've heard if you eat edible flowers, then then don't smell as bad.
Febreezing your butt cheeks helps.
On a side note—spraying Downy Wrinkle Releaser on your face does not work. I tried it.
