<p>The objective of this research was to describe preparatory conversations with adolescents for participation in a group on sexuality. Two researchers and 11 adolescents, aged between 12 and 14 participated. The conversations were guided by a semi-structured script, recorded in audios and later transcribed. The analysis was based on the guidelines of the collaborative practices and was developed based on a construction of two thematic axes: <em>how to talk</em> and what is <em>talked</em> <em>about</em>. We realized that for adolescents, the facilitators' posture should be welcoming, providing a respectful space, reducing constraints. About the content, the adolescents said that it is possible to talk about any subject, with accessible and friendly language. We perceive the preparatory conversations favors the collaborative construction of the group proposal.</p>
