This book critically examines the concept of sexualised governmentalities, a framework for understanding the evolving discourse and power dynamics surrounding discrimination on the basis of sexual practices. Central to this exploration is the shift from traditional heteronormative perspectives to a more complex hetero/homonormative context, where the structure and organisation of sexual relationships gain prominence over the gender or sexual orientation of the participants. A key focus of the book is the concept of homosexism within the realm of gay masculinity studies. The author discusses homosexism as a form of discrimination experienced by gay men from other gay men, highlighting the influence of heteronormative patriarchal society on these interactions. It calls for a broader recognition and acceptance of diverse sexual expressions and challenges the reader to re-evaluate the societal norms around masculinity and sexual behaviour. Sexualised Governmentalities is an important contribution to the discourse on sexual identity and practice, offering insights for a more inclusive and empathetic understanding of sexual diversity.
