Is it normal that i like soiled sanitary pads?

I grew up in a household as the younger of two children – I had one sister who was three years older than I was. She didn’t have much time for an annoying younger brother, as you can imagine, and up until I hit puberty (at around age 12) I didn’t think much of her, either.

Then puberty, something changed. I remember being in the bathroom, washing my hands before dinner, and an intoxicating aroma suddenly hit my nostrils. It was a sharp smell, almost metallic, and as soon as I smelled it I knew it was unlike anything I’d come across before. It was nearby, so I followed my nose throughout the bathroom before eventually realising the scent was coming from the small bin we kept under the sink. What could it be? I had no idea, but curiosity got the better of me and I opened the lid to look. Inside was one of my sisters soiled sanitary pads – she must have just put it in there, the smell was intoxicatingly fresh. I couldn’t help myself with what happened next. Before I knew what I was doing, before I could even wonder at the craziness of my next move, I’d reached right into the trash can, grabbed the bloody pad and stuck it in my mouth. I couldn’t believe it; on one hand the taste, oh god what a taste! I was in ecstasy, but at the same time immediately I was wracked with guilt.

I chewed and chewed, enjoying the heady sensation of that delicious menstrual blood. Even if I wanted to stop, and it felt so wrong, stopping now was beyond my power. I stood hunched over the bathroom basin, my mouth filled with my guilty, forbidden pleasure. That was ten years ago now and I haven’t stopped – if anything it’s gotten worse.

I hope its normal that I enjoy this. I don't think I will ever be able to stop. Does anyone else indulge in this forbidden pleasure?
