It was good that you stayed with your husband because he sounds like he has wonderful traits. It's normal to think of someone you have attraction and desire for. If there is a way you can channel that energy into your bedroom with your husband that would be ideal. You can change your thoughts to perhaps think about any time in the past that your husband was exciting to you. You can incorporate a vibrator into your lovemaking to keep the stimulation going as well. This is very useful if your mind isn't helping your body participate.
