Guess because most straight fiction, presents the smut scenes as quite degrading to women characters and depict them as being very male led/end when he gets his satisfaction. Whereas yaoi, yuri or fendom removes women from being confronted by such awful portrayals.
Some yuri though is for the "male gaze" or least shows some very het dynamics, which like yaoi, a straight audience can relate to more.The whole "uke and seme" stereotypes where one character sorry to be tmi sticks their fingers into another violently and she ends up screaming in pleasure like that scene from Sally met harry lol come on, it's no better than yaoi where only one character can bottom and gets screaming crying pleasure from that alone, all the time.
There are yes, some good yuri that is written by and for women, tackling social issues and women's experiences rather than just straight up unrealistic smut.... but it's rare to find decent translated yuri... the most introspective and realistic is probably "my lesbian experience with loneliness" (think that's the title) which is very very different to say the unrealistic smut of "just right there". Guess it's like the bara on here that doesn't depict male characters as "ukes and semes" and tackles proper issues.
The Q word for many is still considered a slur, rather than an identity. If you self-identify as it, cool, but many in the LGB community would rather just be known as lesbian, gay or bisexual.
I see everyone ragging about how disgusting she is for raping him and stuff like that, and im here horny af cuz of that, i know is wrong and i would never hurt someone like that but still love it
