• He has sexual insecurities.
• He has found someone else and is distracted.
• He’s not attracted or emotionally connected enough to his partner.
• He’s trying to hide the fact that they are drifting apart.
• He’s trying to keep his different sexual orientation in the closet.
• He believes that having an orgasm shows that he’s manly.
