I think one of the big problem is that there is way too much gay and asexual people in the dwarven society. I'm always glad to see homosexuality being present in my video games but the percentage of homosexual dwarves should be the usual 5% of the overall pop, not a majority of them. In my last fortress, the only mariage I had was a gay one, I suppose those two dudes was preventing the heteros from marrying because the thought of a heterosexual mariage would have harmed the "sanctity of their union" or something like that.
I find the 10 year difference already strange, especially for people that can live up to two hundred years, there is no need for more restriction.
I recalled that it was maybe 1% asexual, 10% gay, and 1% bisexual if I am up to date. I'll check the wiki, but personally I like the change. I would prefer bisexual dwarfs being the mode, but ah well.
One of the issues with your fort rather than the psuedo-political belief I'm not sure is possible in game (and probably should never be added), but rather an issue centered around proximity.
The one thing Toady made more accurate is relationship dynamics. I learned in one of my PSY classes that familiarity breeds like, and proximity breeds familiarity. If you spend your time around someone who likes stuff, and you like stuff, and some of that stuff is the same, you are much more likely to be in a relationship together, or to become close with them rather than someone you literally just met who dislikes everything you like.
It's more apparent this version, but when I first started playing 2 years ago, I noticed that friendships weren't easy to start, much less relationships. My marriages were usually migrant ones. I did have 1 marriage, just one.
It was 2 miners who were almost always next to each other. They worked together, probably ate together, and so it made sense that they got married together.
The issue most likely isn't that your dorfs are all the wrong sexualities, just that they probably don't have much time to mingle, or many places. Your happily married (unless they are having fun) gay dorfs are likely coworkers.
It is believed that this makes 71.2% of dwarves strictly heterosexual, 23.8% bisexual, 3.8% asexual, and 1.2% strictly homosexual
Nah, the wiki talks about the sexuality that is believed, as someone
did the math.
In all honesty I see where you're coming from, but you've got maybe a quarter of the population who isn't likely to be making babies, with FUN existing, it really doesn't matter.
Though I really would rather Dwarves being able to have children out of wedlock, shortsword weddings, and even gold diggers. Oh and I do agree the age difference is really silly. A 50 year age difference works better, though maybe when it's a vampire the age difference no longer exists.
