Couples having a child for the first time often experience an impact on their sex lives. In this study they saw that it is a phenomenon that lasts an average of 12 months, and mainly affects libido. Despite a lack of sexual appetite, the vast majority of couples had returned to having sex at a normal rhythm for them by 6 months. Once sex was started again, no problems of pain, discomfort, or satisfaction were detected. They conclude by saying that physicians have to be more aware of this phenomenon and, in the face of persistence, offer tools and support.
I work with a private psychologist / sexologist who could help you if you have problems of this type or in other aspects of your sex life.
