Who are you writing the blog for? If you're writing for gay men then I'd suggest you'd better sound as if you're gay. Now when I'm talking to my buddies, I don't say, "So last night I saw this gay hunk at the baths and ..."

I'd try and speak as naturally as you can. Obviously you're going to want to use the word "gay" to pull in some search engine traffic, but I think a lot of people go overboard.
