Lately I feel like my SO doesn't want to have sex with me, and I know it's all in my head but I can't stop. We still have sex everyday or every other day. He still flirts with me, but once we start having sex I feel like nothing I do is good enough and that he wishes I was someone else or at least better in bed. I don't want to mention it to him bc like I said nothing in his behavior has changed to warrant me thinking like this. But it's getting to the point that even when I intiate sex I can't enjoy myself. I feel like he does all the work and I know he wants me to do more but I just can't keep up with him and I'm so weak that being on top isn't as fun as he wants it to be. Idk has anyone else gone through this? How did you stop thinking like this?
