So often we can hear that kinds of question my boy-friend/ husband has no interest in sex or he can not perform better.
We sometimes have the idea that for men, the sexual experience is detached from what is going on inside. In reality, a man's emotions can have a huge impact on his sexual desire. If he feels emotionally distant from his wife, and especially if he feels like a failure in any way, it can lead to a lack of confidence and therefore a lack of interest in sex. For a man, sexual performance is very much tied to ego, so if he is not feeling good about himself it will definitely show up in his approach to sexual intimacy with his wife.
