He put his profile out there for everyone to see. That's the idea in the first place. Why do you think he would be embarrassed or feel uncomfortable about it if someone were to see it. Did your roommate who you say is/was on the same service ever express a feeling of embarrassment about his or her profile?
If you are the one having doubts about this, you should not bring it up at all any time soon. If you do bring it up later on and he is living up to his profile and you approve, let him know and complement him about it.
HOOP! (Just getting rid of my wooden nickles worth)
