Out of pure curiosity. (▰˘◡˘▰) I got the feeling that for most people is not the case.
For me, I actually read BL because I see and feel represented by soft ukes (and omegas) their "feminine" coded qualities resonate with me in a way I haven't found anywhere else. Most content for gay men (the closest group I could belong to) tends to be hypermasculine and I can't connect with it.
