My roommate smells horrendous - r/college

This is my (19M) first semester of college. I have my own bedroom but share a bathroom with another suitemate (M). He seems very introverted as he has never talked to me even when I try to start a conversation. I say this because I have no idea if I should bring up the terrible smell he radiates. I think it could be a yeast infection but I'm not sure. He stinks up the bathroom so badly I will not even use it. If you are within a couple feet of him you can smell the strong odor. I don't know what to do. I am paranoid he is going to make me and my belongings smell, too, and I don't want to spend the entire semester going to the rec center to use the bathroom in attempt to avoid the smell. I'm new to college, so I am not sure if these things are common. I would love to hear some recommendations. It is really awkward because this kid will not even talk to me, so bringing up how bad he smells sounds like a terrible way to start things off.
