I live in a country where they are everywhere! 
Sometimes, you can't really tell if they are or
aren't even!
They are some of the nicest people I've known. They are usually
very patient, sympathetic, good conversationalists, helpful and
frank, especially the gays.
In my job, I get exposed to all sorts, and there are colleagues as
well as patients and their visitors, who are homosexuals. There was
actually one lesbian couple in particular, who were so commited and
devoted to each other that they made me think, hmmm... (This was
right after I broke up with my fireman!
) Sometimes and in certain areas, you can relate to
someone of your own sex much better. Homosexuals are most likely
people who couldn't find fulfillment in heterosexual relationships
and/or they identify much better with people of the same sex.
I have my views about homosexuality, but I shan't impose them on
anyone other than myself. I have discovered that by not judging
them, but to get to know them as an individual first, you can end
up with another buddy to add to your list. There are two gay
colleagues that I just love to bits because they are just such
awesome and helpful people! 
I do understand what you're saying about feeling a tad queasy going
out with a gay. I might feel the same way going out with a Lesbian,
for instance! But the
thing is to try and look beyond this, and see them as a person and
block out the bits about their sexual orientation that you cannot
stomach.
BTW, I do have an ex whose behaviour makes me wonder, till this
day, if he is a closet gay or a homosexual who hasn't come to terms
with his homosexuality!
Sweet relief I didn't marry him!!!
