Healthy sexual outlook book recommendations

Hi everyone! I’m a straight male(32)and I am looking for books, maybe even with a philosophical approach to having a healthy and realistic outlook about sex/intimacy within relationships. Something that may offer advice about quality over quantity, expectations and boundaries and how to be a better sexual partner. I spent my teenage and young adolescence years as a very unguided individual and now in my 30’s I have been on a journey of self growth. My goals are to change and unlearn the bad habits and replace them with healthier and positive ones. Any recommendations would be greatly welcomed and appreciated. Have an excellent day!
