I've been into Yuri for ages, and it does seem like a lot of guys like Yuri because "omg hot girls" but there are other female Yuri những người hâm mộ out there, like me! I've always wanted to be a member of a female Yuri người hâm mộ club though, so I don't feel so weird, in a sea of fanboys... Hi from a fellow fem Yuri lover, though!
Probably most of them, but it's like how a lot of girls are Yaoi fans. Anywho, I myself am a girl and like both, though good old hetero romance is always appreciated as well. (Sorry if that seemed an insensitive way to refer to it ;-;) Bullt like already mentioned, there are definitely some female yuri fans.
I'm a male and a yuri fan, and from what I've seen from interacting with other people is that most yuri những người hâm mộ are female (or at least females will let others know thêm than males will). I haven't really seen males that will openly admit they are yuri những người hâm mộ in person, but it's always reassuring knowing there are other male yuri fans. Either way, I wouldn't say I feel out of place, but I am hesitant to bring it up sometimes, which is sad.
