That could be. I looked up stats and in the U.S. it's supposed to be 4.5 percent, but that's a new record. And among millennials, it's 8.2 percent! So the trend is moving in that direction, which was the point I intended to make.
It's difficult to gauge what it is world wide--I only see breakdowns by nation, In Brazil, 15 percent of men and 13 percent of women reported same sex attraction. Stats vary for various countries. .
