Lingerie

My boyfriend and my anniversary is coming up. I'm planning to buy some sexy lingerie and make it special for him. Only problem is I've never worn any before. I don't know how to do it. Sexiness seems to come naturally to some people. But not me. I know I have a nice body. But I'm just super timid. How can I be sexier and how can I pull off the lingerie to make the night amazing for both of us?
