Why are most teens gay?
No, most teens are NOT gay. Most teens are straight.
But about 10% of teens are probably gay. That's quite a
number.
*Edit: It's largely believed amongst gay people that 10% of the
world population is gay, which is a grand exageration. In fact,
less than 1% of the world population is considered gay, and less
than 2% of the western and modern world.
A 10% of the population being gay (or even more) is possible in
concentrated regions like San Francisco (USA) and other key places
in the world.
San Francisco is the world's best and largest known place with a
high concentration of gay people living there.
