What are some fundamental books on sexuality ?

Hey I'm pretty new to this topic but my asshat flatmate won't stop making weird arguments (redpill-lite) on this topic and I want to be armed with something substantial. What are some important books I can read on this massive topic  ? Any important books under this umbrella is good for me.

*Three Essays on the Theory of Sexuality* by Sigmund Freud

*The Second Sex* by Simone de Beauvoir

*Gender Trouble* by Judith Butler

*The History of Sexuality* by Michel Foucault

*What IS Sex* by Alenka Zupančič

Some of the works mentioned are not strictly philosophical, but they are essential reads—after all, sexuality cannot be conceptualized without psychoanalysis.
