Chat Roulette is pretty much the original destination on the web if you want to meet and greet other people. Chat Roulette was actually created by a 17-year old kid who went on to sell it for a heap of cash. Today, it's used by those that want to meet strangers and talk shop. It's anonymous, free to use and you can move on to a new user at any moment using the 'next' feature. You might find it hard to come across gay people to chat to, but as soon as you work out the interests feature it's not so hard.
Note that Chat Roulette was not designed to be used for gay guys, nor those that want to strip down and have a good time. Chat Roulette's a much more broad-minded chat website, but of course, you can still find cybersex if that's what you're interested in. I actually go on Chat Roulette myself from time to time, but I opt just to chat with people and have a good time. All in all, it's a good experience and I think everyone should have some gay cybersex at least once in their lives.
