was this sexual assault?

I went to a psychiatrist and she was asking about any sexual abuse i endured. I was molested when i was younger, so she had asked if anything had happened when i was older. i told her i didn’t think so and she asked what i meant by that. over the summer i went to a friends house, who lived with 2 other guys i worked with. we were all drinking, and i ended up getting pretty drunk. i remember being outside with everyone and then i remember nothing after that. when i “sobered” up i was in one of her roommates room with his penis in my mouth. i remember feeling so drunk that i was basically passing out on him. i kept telling him to stop when i would move away but he would grab my head and push me back. I didn’t really think anything of it up until i spoke about it. was i assaulted?
