It was a line used by Robert Schimmel during his comedy act for Unprotected. This is what he told the Doctor while he was getting a Sigmoidoscpy. "I taste metal" get the device out of my ass or who knows what the future my bring... ...

I wonder do the females "taste metal" during their anal scenes? Do they look at the director and tell them... Yeah, can we stop for a second. Maybe there's a time out signal like in the NFL....

Or do they just close their eyes and power through it?

I have scenes from Gang Bang Girl 18. That prove different. ...Sabrina Johnson is getting nailed in doggie and you can see this "baby food" just dripping out of her ass, down her pussy and onto the floor. WOW
Sean Michael has to dab her with a towel 2-3 times during the scene.

Again in Un-Natural Sex 12. Taylor Rain is getting hammered and then both guys strike oil. But, Chico Wang keeps filming. Anabolic does not specialize in couples porn (Trust). I've heard the stories about talent doing enemas or not eating for 6 hours before an anal scene....Does that really work....

Robert Schimmel=greatness

Sorry Cleetus. I guess I'm the evil twin.
Hey, maybe it's more like Tomax & Xamot....
