Interesting question, and it does actually have somewhat of a pattern in the answer.
Gay MEN are some of our very best customers for art and "home stuff." Gay WOMEN are probably quite a bit below average.
That's a generalization, of course... with its exceptions.
Interesting... would not have guessed that on average there was that much of a noticeable difference (between the two generalizations). But for these couples, you would say both partner's behavior was more or less the same?
And now I'm also curious to hear the breakdown by racial groups as well as foreigners vs. US travelers vs. locals, hah. The most "forbidden" topics of conversation happen to be the most interesting to me :P
