I hate having sex

Hate is a strong word. But I’m very annoyed with even the thought of having sex. A few months ago, I loved it wanted it all the time. Then it started to get uncomfortable 😣. Now I have absolutely no sex drive. No pleasure, no excitement, no feeling. My SO tried to buy a toy to I guess help me and spice things up but honestly the first time was okay. The most recent (tonight) I was completely uninterested. He was inside me and I felt numb like ntn was going on. I was scared to let him in. I’m never “in the mood”. What’s going on with me 😣😞
