@SW-User My main to that would be that you don't need something to be the "majority" in order to have gay characters. For instance, in my area I could say most people are straight but I've seen more a few gay couples and more than a few individually gay men depending on area so I don't get what's far fetched about writing them into a story or a narrative. This is my main point.
I do want to touch on a few points about statistics. There's significant differences across generations rather than just one generation so statistics are hard to quantify. Plus, you got countries that are heavily anti gay that even if there was polling that took place, people may not want to identify as their correct orientation. Some person can appear straight but also be bi, gay, trans or whatever on account of being afraid of their own families. This is also seen in older generations where being gay wasn't accepted.
All this skews statistics. For instance, there have been gay pastors they are uncomfortable with their orientation so this may come out as anti gay Evangelical fervor and they appear straight all the time, but they're not. In the media they are always found out as gay, this is where the term of internalized homophobia comes from because it's time tested proof things like that exist.
Also, even if straight people are a larger portion of the majority which I don't argue because I literally don't care as I accept it's a natural state of the universe unlike anti gay people, I am not sure as to the percentage of people who explored their sexuality to find that they were straight.
I'm not saying all straight people would do this but I don't know the percentage of people who, let's say, fantasize about same sex or are curious or exploring.
Things get kind of muddied that way when you introduce those components because orientation is a little complicated. Which is why I'm not sure we can rely on statistics in any quantifiable way of "just pure straight people" or "primarily straight but explored same sex relations."
I'm sure there are plenty who are "purely heterosexual" but what I'm not sure of is statistics and normalcy of any one orientation.
