Portland dorm life?

Portland itself seems very liberal and some of the universities there allow coed dorming. Not coed buildings, not coed floors, I’m talking about coed rooms. Portland State University is the one applying to and they are participating in this. So my question is: Is it exactly how I just described? Can girlfriend and boyfriend students live together? Is this right ? I hope I’m not missing or misinterpreting something. I’ve read a view answers on the internet but I decided to check here if you guys knew or maybe just can look it up better than I can.
Thanks in advance
