I know I didn't care, and neither did my frosh roomie, but we had bunk beds and would have full on sex with the other person in the room, if you got too loud, you'd just be sex-iled, or ask to join... either way it quieted down.
.. And probably lead to a lot less masturbation and a lot more sex.
I went to boarding school as well as college. Every roomate except for one was comfortable about jerking off. Neither of us minded if the other had a hard on or if they stood there and let their nuts go. A fw times it led to some good sucking with one guy.
FWIW, I agree 110%. They gave me reason to live growing up! My old school has divided the old gang shower room into stalls now. Tragic.Likewise, all dorms should have communal showers.
