As a physician, I must weigh in, contrary to what the previous individual said, your consumption of shell fish can affect your mate. The most common instances are semen deposits causing a reaction in the recipient, however it has been shown to cause affect if the female's partner is allergic. There is no real answer to how long it will stay in your system, however, you must be cautious and keep shellfish consumption to a minimum until you know how it will affect your partner, if at all.

Well, the good news is that most relationships don't last. I predict you'll be back to eating shrimp and crab in no time! In the mean time, would imitation crab be of any help?

For some weird demented reason, this question made me think of Kip Addotta's Wet Dream:

I invited her up to my place for a little midnight bait. I said, "C'mon baby, it'll only take a few minnows." She threw me that same old line: "Not tonight, I got a haddock."

And she wasn't kidding, either, cause in came the biggest, meanest looking haddock I'd ever seen come down the pike. He was covered with mussels. He came over to me; he said, "Listen, Shrimp. Don't you come trollin' around here." What a crab. This guy was steamed. I could see the anchor in his eyes.

I turned to him and I said, "Abalone! You're just being shellfish." Well, I knew there was going to be trouble, and so did Gill, cause he was already on the phone to the cods. The haddock hits me with a sucker punch. I catch him with a left hook. He eels over. It was a fluke, but there he was, lying on the deck, flat as a mackerel, kelpless.
