I've had the same thing for 20 years now, started when I was 14. I've tried the Flat-D pads but usually by the afternoon they loose their effectiveness and also they seem to have to be positioned just right; they must be flush against the skin but there is no seal so gas can still get out around them when you move around. I've bought a pair of shreddies (I've read alot of good things about them) they have a low waist band though I'm use to the granny panty where the waist band comes up to your navel. I'm wearing a pair now, I didn't get the sizing right so i'm wearing my flexes panty on top of them to hold the shreddies flush against my skin, so far so good. I am going to try the product Whiff, has anyone else tried it? It actually is suppose to effect the smell of fecies and flatulence.
