Marriage & Sex

So The Hubs & I are coming up to our 1 year anniversary of being married. We were on a road trip this weekend and we talked the whole way about a lot of things. Sex was one of those subjects. I've always been very timid and shy when it comes to sex. He told me that i'm not consistent when it comes to our sex life. Like i'll be on a good streak for a couple days then fall off for a few weeks. He's not complaining but he does want me to feel more comfortable and confident with myself and with him during our intimate times. Any advice/tips? I really do try and I feel like I've gotten better since the very first time. But i know i could be better and I want to be better. I mean he's my husband and I love him.
