From what I see in the younger members of the MSM community in Norway, this is true. While they use condoms at times, I know plenty of people in their 20s who admit that they don't always use condoms, even outside of committed relationships.

Granted, this procedure is only helpful for the community if it actually is shown to reduce the risk of HIV transmission, and it's not a cure, but anything that helps reduce the risk is a good thing.
