This is a list of books on the history of sexuality or queer history (that I’m aware of) that include m/m topics. This will not include books that are solely about m/m queer history because they fall outside my scope of interest. This list was compiled to answer a query on social media (and was too long to post there in response). Because the question was focused around 12th century France, I’ve bolded the titles that have specific coverage of the middle ages.
