(M29) (F25) Recently my girlfriend of 3 years said I’ve never been able to “fuck” her good while heavily intoxicated. How do I proceed?

Girlfriend of three years had quite the drunken night which ended with her stating I’ve never been able to fuck her good. Never seen this behavior from her. I’m afraid I’ll never be able to comfortably have sex with her again. I’ve literally given all I have to our relationship. In the past I’ve introduced toys and tried to stimulate her with other means. (I’m not very well endowed). She has bragged about her sex life with her ex boyfriend on multiple occasions. How long he lasted and how much experience she gained from him. Please any advice would help!
