I agree that perhaps there should have been a "None of the Above" option, but I think the poll is ok like it is too. Either way, it's a private poll.
As far as defining whether the other person was of the same gender or not, I did not have a lot of space in the polls' heading to define all the parameters. I could have detailed that a bit more in the opening remarks. Still, I think people get the overall gist of it...at least it seems so from the previous responses.
And yes, there are things that people wouldn't do in the presence of a homosexual person or even a heterosexual person, for that matter, such as anything having to do with nudity, simply because people tend to be self-conscience of their bodies, generally speaking.
Though there are people who would voluntarily "swing it around"
for just about anyone if they were given the opportunity, most people are not exhibitionists. And too, many people feel as if a homosexual of the same gender is the equivalent of a person of the opposite gender, when it comes to certain issues (such as nudity).
When it comes to sexuality and nudity, this is where America is much different as a society, than say some European countries. I remember years ago when I went to get a massage from a Russian female. Besides the pain she inflicted on me, she also was a bit insulting, constantly telling me to relax, "You Americans are the most self-conscious of your bodies!" She told me that in Russia her clients did not use a towel; however in America, she has to cover the areas that she isn't massaging. She was nice, even through her ranting, and I learned something that day about the difference of perception in Americans and other Europeans.
Perhaps it is for similar reasons that the United States' military does not allow open homosexuality yet. Many people compare the US military to other European nations, which allow open homosexuality, but they don't take into consideration the differences in overall perceptions (of the people in the different countries). ...just look at the commercials! The Europeans are much more accepting of public nudity than Americans.
(Sorry--I just had to throw that comment in there about "swinging it around". I thought it was funny.)
