When the mrs and I first hooked up, we did it a couple times. However, contraception has always affected her period by eliminating it. Once in a blue moon, she may have a real light flow. It's rare though. She's been on depo, pills, and now, an iud. As I recall, it usually didn't smell, though there was once or twice when I recall it did.

As for the red wings, I got mine...work boots!!! Puke, that's nasty. I'm into kinky oral stuff and what not, but that's just gross. Poop, urine, and blood waste have no place in my mouth. But if that floats your boat, kudos to you and party on, Garth.
