One of my best friends is at a different school than me and he is having some issues with his roommate this year... i will quote what he put on yahoo answers
I'm in college and am currently randomly assigned to a very weird roommate. This kid is very awkward and nerdy, and while I am okay with this, he also masturbates a disturbing amount. Our garbage can is filled with what are clearly his used masturbation tissues and our room is starting to have a weird musk. Outside of this he is a very good roommate and I am not sure how to approach him about this without offending him but this needs to stop!
