What Causes Lack Of Libido While Having Hyperthyroidism?

Hi doctor, My husband has always been very addicted to porn.. iv been married for 3 and a half yrs.. initially our sex life was perfect and really fulfilling but in the last 2 yrs I don t seem to enjoy anything anymore. I literally feel banged up. And he is unable to cum if he moves slowly.. I am completely sore every single time. Unfortunately due to a high level of thyroid (61) I very rarely even feel like having intercourse and now when we do I don t enjoy it at all Loosing hope now. Don t know what to do. We have been planning too but no results yet
