It could happen when you have the least amount of time available for it.
Someone comes out to you. He may even hit on you. He thinks he wants a
lover, or maybe just to get laid, but you know better. What he needs is a
mentor.
He needs someone to explain things to him. Someone with patience and
wisdom. And whether believe it or not, you are that guy. You can do it.
You can be his mentor.
Remember back when you came out. It may not have been the first time or
even the second, but early on in your gay experience, someone took you
under his wing and explained things to you. He answered questions you
couldn't look up in the encyclopedia. Hell, he even answered questions
you didn't even think to ask!
And even if you didn't have your own personal mentor, don't you wish you
had?
You have an obligation to make sure that this guy comes out of the closet
right. Explain that inside language we have -- the Queen's English --
that "coming out" doesn't mean leaving, it means arriving. Tell
him what scat, fisting, watersports and tearooms are. Tell him that real
men do kiss, each other!
Tell him that at least a few times in his life someone else will come out
to him and that he has an obligation to show the same patience and
understanding that you've given him. You and he are part of a chain of
understanding that goes clear back to the beginnings of
humanity.
For awhile he will become your buddy. A constant companion, even though
you may not want even want one.
Eventually the two of you will grow apart. He will no longer need you as
his mentor. There may come a time when you never hear from him again. But
it's okay. You'll know that he's all right. You've given him the
knowledge he needs to survive this gay world.
