This study sets out to discuss the emergence of the profession of sexologist in Portugal, comparing its development with international trends. This research also seeks to understand the self-identification of sexologists and the significances they attribute to it. The empirical information presented derives from a survey conducted with 91 Portuguese sexologists identified through the leading professional associations and from 44 in-depth interviews with experts selected by intentional sampling to ensure the diversity of Portuguese sexologists. The results of the survey indicate that the Portuguese sexologist is on average 43 years old, mainly female, non-physician, and has training in sexology. Considering the qualifications of the interviewees, their professional trajectories and the activities they develop in the field, and the discourses related to their ideals of the profession, a typology was found with five types: sexologists by vocation, sexologist by clinical practice, sexologists by certification, social scientist-sexologists and sexologists by media coverage. The survey identified an interesting diversity of practices and professional conceptions in the field of sexology in Portugal. Being a sexologist appears to be more associated with the ideals of the profession than the time devoted to same.
