Abstract The scientific literature indicates that chronic pain influences the sex life of women. The objective of this research was to describe the changes in the erotic expression of a group of women with fibromyalgia. For this, a qualitative study of interpretive phenomenological design was conducted in which 15 women were interviewed in depth. Some participants said that the appearance of the disease was an opportunity to strengthen their relationship. Others said that their partners’ indifference and skepticism about the disease, as well as the lack of understanding in the sexual sphere, acted as barriers in the relationship. Sexual intercourse was perceived as an obligation associated with gender or as an irrelevant dimension. Sensory stimulation and preliminary sexual play were strategies that allowed them to adjust and promote mutual enjoyment. The position taken by women in the face of disease influences the erotic expression.
