According to what source women who read yuri end up marrying men? Also how do you know they don't do that because of societal pressures? The pressure to marry a man in Japan is intense.
I said dating, not marrying. I haven't read anything about marriage. The survey was commissioned by some research department and targeted girls in school and college. They asked them if they were into yuri, then about their own romantic experiences. Many said they were dating boys. Nobody asked them why, so yeah, the reason for that could be societal expectations. (Of course, there's no law that says hetero or bi girls can't enjoy yuri, so perhaps they simply were that way...)
If I remember correctly, there was this survey of Dynasty Reader a few years ago, well before I even knew this site existed, and in that survey there was something about the demographics of the site and which works are most popular within a demographic, and what do people like most about yuri manga. I remember that there were 5 demographics. These were (in decreasing order of size): non-straight female, straight male, non-straight male, trans/non-binary, straight female.
So, yeah, not only are there straight girls who read yuri manga, but there are even a few on this site.
and there are only two possible responses to a fetish: 'Yay!' and 'Huh?'
You're forgetting option three: "burn in hell, blasphemer".
Ouch. It's true and it hurts. :-(
