I would suggest basically showing that if he does come out you will be supportive, and nothing would change for the worse between you. You could do something like talk or post (on facebook etc.) about how you are in favor of gays being able to marry and having other rights everyone else has. You could even say (privately ofc) something like "I just want you to know, you're a really good friend of mine, and that wouldn't change at all if it turned out you were gay or bi." Don't push the point or say it over and over, just try to be clear that if he did decide to tell people he was gay/bi you wouldn't have any problem with it.
