Erotica-Not as Easy as it Looks!

Just ask my editor. I have the most difficult time writing a simple love scene. I feel all flushed and uncomfortable and can't write with anyone else in the room. She has to pull the lines of the scene from me one by one like pulling teeth.
So now I've set myself the ultimate challenge. To write a short story, a la erotica. Heavens, my mouth goes dry just thinking of it. And honestly, there's just some words I cannot say let alone write down on paper. Did the temperature in the room just go up?
But like any phobia, maybe if I immerse myself in satin sheets and feather pillows then maybe the next love scene I write can be done with less embarrassment and more gentleness.
I wonder what magazine I should send the story too...
