I know it's weird, but I don't like blowjobs. Maybe if I'm about to cum, but I just don't like being still during sex, and the only thing that can get me off besides penetration is masturbating. I also have ADHD, so that may be part of it. When I'm stimulated and I sit still, my mind goes a million places. Oh God, the memories of an ex blowing me and me spacing out and forgetting she was blowing me and going flaccid... Ugh.
