I had a client who booked me stressing that he was "straight, but just curious". We visited about his lack of "background" with anything gay and that I would need to "take it easy and be a teacher". I can tell you he was anything but naive. I realized immediately, it was about trying to create something that wasn't reality. The booking went well, but that his "straight, teach me" illusion was just that. Now obviously this isn't a case of "hiring a straight provider" (I wouldn't be doing that as a provider), so this is about as close as it gets for me.
