Basically, yes. Depending on the site they'll have rooms or keywords to help classify the guys - muscles, dildo play, bdsm, etc. Some you tip to perform a specific task, show armpit, flash cock (they'll have a menu). some you can tip and ask them to do something. many will go into a private room with just you and him for a per minute rate and will do things. it can get addictive, especially if you find a guy or 5 that you like and your interests click. I'm sure there are more variations on the theme out there.
