Suggest me a book to help with my avoidance of sex with my partner

I routinely avoid sex with my partner who I love and am attracted to sexually. I have sexual thoughts about my partner but I find having sex to be transactional and often not worth the time so I don’t initiate. When he asks for sex I feel as though he is using me even though he has tried to help me understand it is an opportunity to pleasure each other and feel good about our relationship. I do have sexual trauma and my previous partner had a sex addiction/porn addiction that severely damaged me and ended our relationship. I would like to read a book about how I can work through this and also understand why I might feel this way about sex.
