The physical, emotional, and social changes associated with pregnancy and the postpartum can affect sexuality. During this time, sexual desire, pleasure, and activity often diminish. Sexual dysfunctions can also appear. Active intervention by health professionals, based on respect and empathy and following a biopsychosocial approach, can help improve sexuality. Normalizing the physical and emotional changes of this period, and dismantling prejudices and erroneous beliefs about sexuality during pregnancy, we can dispel many fears and doubts, improving self-confidence and self-esteem and reducing stress and anxiety. The most important aspect in achieving a satisfactory sexuality is the quality of the couple’s relationship. Therefore, we must help both members to improve their emotional approach. In a normal pregnancy, sexual activity is safe and healthy. Adequate sexual health during pregnancy provides important benefits: it reduces stress levels, maintains adequate self-esteem, and enhances intimacy and complicity in the couple’s relationship, thus improving overall well-being.
