First of all, I wouldn't jump to conclusions. Maybe he was doing a search for a gay friend of his who was at work or something.
I mean, you'd be surprised at some of the gay stuff in my search history.... all for perfectly innocent distrations. In fact, I just checked my history and out of the last 12 hits, 9 of them are about gay porn sites and one is a e-harmony-like site for gay singles.
I'm not gay or anything, but I am an art aficionado, and gay porn is often very artful itself, or has links to pages that have majestic pieces of artwork which can be appreciated by homosexuals and heterosexuals alike. For instance, one of my favorite sites, "Hogz 'n' Ballz 4 Him" is very rich in color schemes that sets a mood for almost any occasion... Especially occasions where gay sex is involved.
And "Back Door Firemen" provides the crispest imagery that you have ever seen! Anyone who appreciates good photography should visit that site. I don't know what kind of cameras they use, but they're of even better quality than the "Bend Your Gay Ass Over You ####in' ######", which are phenomenal.
And if you're a web designer or a web-surfer who just likes to visit well designed, streamlined and attractive websites, you should check out, "Mollywhomp Me With Your Meatpole While I Yank Your Scro", because you'll find some of the most professional and clever web-development around.
Even better than the design on "Jizzy-beards" which won awards for several years running.
So don't jump to conclusions. Just because you visit "Hairy Meatholes", "#### Duals" or "Drown Your Gay-Ass in an Ocean of Love-Juice" doesn't mean you're gay or plan on cheating on your wife when you visit Las Vegas.
