BDSM sexual practices related to sadomasochism, domination and submission, represent a vast range of possibilities in terms of paraphernalia, associated emotions, uses and applications that are as diverse as the human beings who practice it. Taking this into account, we conducted a study to understand the practices related to BDSM, under the perspective of its own practitioners. For this, a qualitative methodology was used, with an emergent and projected type of design. We covered 8 in-depth interviews on men and women from Venezuela and the data was analyzed through the constant comparison method in order to generate grounded theory, this paper comes up as part of a larger study. Among the most outstanding findings were the importance of limits, some as irrefutable an others that are meant to break, and the importance of the physical and mental health conditions in the practice.
