Okay then. If two Stanford students have been drinking, any sexual contact between them will be deemed non-consensual by the university. So they're both in violation of the Student Code of Conduct for sexing while drunk even though one was being demanding and the other was being kind.
Well, the issue with that is that is that it becomes just one more way to discourage reporting rapes. If someone rapes you but you'd been drinking too, having the risk of suspension or expulsion hanging over your head when deciding whether or not to report them is a thing that they don't need to deal with.
