I don't know what to do

I am getting aggravated and I don't know if it's worth it or not. I feel frustrated because I feel like I am always the one to initiate sex with my husband. I feel like he never initiates and that makes me feel unwanted. I get nervous that I'm not attractive to him and that's why he doesn't initiate. I feel like if I never start it then we would go months without having sex. I don't know what to do or how to express these feelings without coming off mean. 😒
