An interesting article. I have a 23-year-old son with what appears to be an active and enthusiastic relationship with a young woman. He quipped after dropping an earlier long standing relationship that he might "go gay" because "gaay was the new cool". I think he was just horny and at that point dealing with another young man seemed easier than untangling himself from his girl friend of the time.
The whole discussion revolves partly around the relative value of labels such as gay, bisexual, and straight.
