Plate dropped this one in a joking way. I did not find it funny though since I suffered from ED and PED during a toxic relationship. I usually last between 5-20 minutes (excluding foreplay). She cums multiple times during sex, sometimes breaking down and her whole body twitches. Even if I cum early because I'm too horny, I usually get hard again after a few minutes and I'm good with my toungue and fingers.
When she dropped the line, I laughed it off, but I still wonder why she said it even though she said it was a joke. After saying that she was scared it made me angry. I feel a little insecure now and sex doesn't feel as good as before.
Edit: Maybe I should add that I'm her first sexual partner while I had plenty before. I know I'm good at sex and all my female partners from the past told me this. Maybe she got wrong expectations (I know she watches a lot of porn) and I should tell her the real world is different
