Does romance die when you decide to have a baby?

My husband is almost 24 and I am 23. We have been together 7 years, and married for 2.5 years. We're considering having a baby. I love our life as it is. We have fun, we go out, we enjoy fine food and wine, but lately I've been craving motherhood. The biggest thing holding me back is that it will cause all romance to die, our sex life will suffer and that we'll grow apart. Honest answers, please!
