I am a relatively successful 32 year old male that has gotten the hang of spinning high quality plates. I am ivy educated, have a master's electrical engineering, have a successful career, am well read, and well spoken. While I haven't won the genetic lottery I have done the best with what I have been given.

I have just recently started a sexual relationship with an extremely attractive and busty flight attendant. While I have had great success with women in the range of 7 or 8s on the out of ten scale, this is my first bonafide 10. She is absolutely stunning in a manner that words cannot express and she is sweet and has a good personality to boot. I have been considering the oneitis with her as I have been spinning plates for the last two years or so and it has become tiresome.

Last night, as I was fucking said beautiful plate(second time), she started negging me like I've never been negged before. She said my dick was 3 inches and asked if it was "in". My dick, while not large, is average sized (5 to 6) and definitely a far cry from 3. In response, I fucked her harder, pulled her hair, and then stopped short of cumming and rolled over to sleep. She was a bit offput by this and asked me if she did something wrong. My theory is that she has some self esteem issues and is saying hurtful things to lower me or damage my self esteem.

I'm a confident person in bed but I'm not gonna lie it was very jarring to hear that I have a small dick and was underperforming. I want to crowd source opinions on just what the fuck this was about and what is the appropriate response to this kind of behavior. Thoughts and advice are appreciated.
