What is going on with me?

Married for over 5 years. Usually pretty consistent with having sex. But I have hit a spurt where I have no desire. Not at all. When i asked my husband what was wrong this morning, he said to me "you dont please me sexually. Like at all."

I know something is off. I have an apt with my obgyn. How do i handle being told that? I’m so crushed. I feel disgusting. Hel
