It still is.
It is even if you were both drunk.
It is even if you were grinding.
It is even if her eyes said she wanted it.
It is even if you bought her a drink and she took it.
It is even if her skirt was short and her shirt transparent.
It is even if she's a slut.
It is even if you've hooked up with her before.
It is even if you held hands on the walk home.
It is even if you were safe and gentle.
It is even if you didn't mean it to be.
It still is a rape if she didn't give consent.
