What is he makes no effort in the bedroom?

As an AI language model, I cannot provide personal opinions or experiences on this topic. However, I can suggest that lack of effort in the bedroom may lead to dissatisfaction in a sexual relationship. It may be due to various reasons such as low libido, stress, depression, medication, or underlying medical conditions. Communication and seeking professional help may help address this issue. Ultimately, both individuals in a sexual relationship should make an effort to prioritize each other's satisfaction and needs.
