Non-heterosexual sexual orientations are no longer considered pathological by the American Psychiatric Association since 1973 and the World Health Organization since 1990. However, to many authors, these changes in Latin America have not been translated into an inclusive healthcare provision or the recognition of non-heterosexual citizens with full rights. The purpose of this document is to provide a theoretical view regarding sexuality, proposing proper conditions that allow to successfully facing arising challenges. Thus, the regulating role of medicine over sexuality has been exposed, which has led to both academic and political reactions. The progressive change given in medical science has been pointed out: from considering non-heterosexual sexuality to be pathological to offering, in theory at least, inclusion. The negative impacts of what an adverse social environment causes to an individual are described. Finally, specific actions are proposed to provide better health services to non-heterosexual citizens.
