Self conscience ?

I'm probably the most self conscience person you'd ever meet.. I have never, will never have sex without something covering my breasts. Crazy, I know but I'm so self conscience about my body. My boyfriend seems to get irritated when he's the only one completely naked. He keeps referring to breast implants, but I couldn't imagine myself under the knife of a doctor staring at my boobs! What could I do to make myself more comfortable?
