Any tips to help me relax????

My husband and I have been married for 2 years and I still feel extremely awkward initiating sex. We waited until marriage for sex and dated 6 years before marriage. I enjoy having sex but I feel unsexy and awkward and very tense and it take a while for me to get comfortable. It got worse after our miscarriage and sometimes I am scared to be intimate. I am extremely attracted to him but I don’t want to have sex every moment of the day like he does.
