Newlywed venting

So my husband and I are both 25 and this is our first marriage. It's been just under 2 months for us and even before getting married my sex drive compared to his was way low. It doesn't make sense to me because before we started dating I was, in a way, very adventurous with my sex life. It's not that he's not attractive to me or anything. I think he is gorgeous. Have since 9th grade! Im sure life is a major player in this but I feel like there might be something else physically causing it. Any ideas or suggestions completely welcome!
