Purpose of Review The purpose of this review is to summarize the current knowledge on sexual desire expressions, sexual orientation, and identity in understudied groups inside the LGBT+ community. Recent Findings Sexual desire and related problems have unique expressions in LGBT+ people which influence their sexual health. Emerging sex-positive approaches might be powerful and prominent tools to provide support and education on behalf of safer sex practices and marginalized sexualities. The importance of deepening LGBT+ sexualities and relationships, not only in lesbian women and gay men but also in all the other shades of the rainbow (bisexual, transgender, asexual, fluid, and non-binary/ genderqueer identities), is strongly highlighted. Summary A lack of literature regarding sexual desire in LGBT+ people is reported. Results are controversial and research is still limited on this topic, with little information available about sexual and health needs of sexual minorities beyond gay and lesbian people.
