This study will examine the psychological burden of changes to sexual wellbeing, sexual identity and intimate relationships in heterosexual and non-heterosexual men with prostate cancer. While previous research has focused on heterosexual men, this study seeks to undertake a comparative analysis of the impact of prostate cancer on the sexual wellbeing of both heterosexual and non-heterosexual men. This comparative study marks a crucial and timely examination of the commonalities and differences in the impact of prostate cancer on men’s sexual wellbeing, and will productively inform specific and tailored health care provision and support.
