Newly Married No Sex Drive

My husband and I got married in January. I wasn't a virgin and he was before we got married which I'm fine with. I know it's definitely going to take time for him to "learn" what my body responds to and what not, but at this point when we are intimate I have difficulty feeling aroused. I love my husband more than anything and I feel like there's something wrong with me and I'm "shirking my wifely duty" because I'm just not interested in sex... I don't know what to do... Is this normal?
