How do I spice up sex life?

Megan
Me and my husband haven't been intimate since I got pregnant and it's killing me! He never wants to have sex but I always am giving him a bj because I don't mind doing it and I do it because I love him. I asked him why he doesn't want to have sex anymore and he said it was because we do the same old things all the time and it's getting boring. He said that pretty much anything to spice it up would work for him but I'm a shy person and I'm not really sure what to do to get him interested and excited. I wish I wasn't so shy! Any help on what I can do to make him interested so I can get our sex life back?
