The number of people that have had a homosexual encounter is closer to 30%. Most don’t stick with it, but that is the number that is rising and that is a major public health concern. The study that showed 2% was a self-identification study, not a behavior study.
30% have experimented with it? Wow.
Could that be because our culture celebrates homosexuality so much, that people want to try it?
What do you describe as a “homosexual encounter”?
To arrive at that number, I'm guessing "encounter" is very loosely defined to the point of being silly.
