Low sexual interest can have many potential causes, from hormonal disruptions to lack of sleep to stress to simply not having great sex (after all, it’s hard to be interested in sex that isn’t working for you). It may be worth consulting with a healthcare provider for this to identify potential underlying health conditions that might be contributing. It may also help to consider lifestyle modifications (e.g., exercise, diet, better sleep schedule) that can help to boost desire. Finally, you might also consider introducing more novelty into the bedroom (such as sex toys) to help ensure that you’re having more exciting sex and sex that’s worth having.
