I went to undergrad 2009-2013.
Freshman year roommate was a guy I knew from the same city. He wore boxers and I think boxer briefs occasionally.
Sophomore year, compete rando and I have no clue.
Junior year was another guy I didn't know but moved off campus to a house. Him and I lived on the first floor and two girls on the second. He had briefs, I was curious only once and looked in his drawer. But I was there for one semester.
Senior year was just me and two girls so yeah lol
