As everyone said, if there was no consent, it's rape, end of story. Period. It doesn't matter if you were drinking. I never understood how people could assault someone and blame it on the alcohol because there's so many steps involved in that act...That and there are people who get drunk and don't assault others. They just literally pass out somewhere. So personally I don't think him being drunk is an excuse to rape you. It doesn't matter if you were both drinking. I REALLY want you to understand that none of this is your fault. You didn't let him do anything. When something dangerous happens to us, we go into fight or flight mode, or sometimes we completely freeze up out of fear. It's a natural response.
I'm very sorry that happened to you. I wish you the best of luck in healing.
