Hopefully you have therapy appt soon. I’d be concerned with a friend thanking your husband for allowing him to watch you. I’d have a talk with my husband that I am not an object and not his property. My body is mine. So if you want to show your naked body, it’s perfectly fine and men can thank you for the opportunity. They shouldn’t thank your husband as it’s not his body. I’d talk about it in therapy to make sure your husband understands that concept .
