Sharing the hotel room with a co-worker non nudist...

So I am on a TDY in Alaska and I have to share the hotel room with my co-worker and it is a bummer. He is not a nudist or practice the clothing optional lifestyle nor are either of us gay, I am married and he has a girlfriend / fiancé. So there is no being nude while we are in the room together, we work different shifts so it is better then nothing. The heater in the room does not work properly because every morning at about 4am the heater blasts full heat for about an hour then goes back to normal. In addition, I am having a terrible time transiting back to wearing clothes while I sleep, they are obnoxious and way to warm. He is also the extremely modest type, which means if I even go without a shirt he avoids looking at me. Which sounds fine but it is awkward at times because he goes out of his way to avoid me with my shirt off. So these next 5 and a half weeks will be irritating but once I make it back to Korea I only have about 6 weeks until I get my mid-tour and can see my wife again.
