Lol, I could have told you that same sex couples get divorced just as much as straight marriages. Just because they are attracted to the same sex doesn’t mean they are more likely to stay married. It’s not so much taboo anymore and if they want to leave they will and find someone else. Maybe they got their divorce…

I don’t think having sex when you don’t want to is healthy in any relationship, married or not, and may create some tension. Sex and intimacy is important in a good marriage, but not forced/unwanted. No one wants to get divorced but in the event that it has to happen you can get free divorce papers online nowadays.
