Crying with laughter.

I'm still a Christian (though don't "identify" - if you'll forgive my use of an obscenity - as evangelical), but the ridiculous way certain Christians I encountered over the years tried to put prudish regulations on the kind of sex one could have is truly preposterous.

My future wife (who was a recent convert at the time) was told this by some pearl-clutching individual. She then asked me, and I told her obviously that was bullshit, entirely unsupported by anything in the Bible (in fact, the Bible even celebrates it if you ask me, just read Song of Solomon and you'll see clear oral sex euphemisms). When I said that, my future wife commented: "Blimey. I feel sorry for her and her husband." :)
