Ok,title not withstanding I do actually have a problem. I've been on the pill (ortho tricyclen) for almost two years now. For the last year or so I've noticed that the fabric in the crotch of my underwear has started to appear brittle, and then to form holes, large holes at which point of course they go in the garbage, it happens to all brands and all fabrics. Any idea what could be causing this? I assume my discharge has become more acidic but has anyone else experienced this?

Thanks
