You might be right in that there are more/ a lot of bi bw, but you're missing the reason why. It's not 'natural' for women to play like that. I don't want to take the joy out of this for yall, but I bet those numbers match the molestation numbers.
Girl who were abused by men- whether physically, sexually, or violently- tend to have (at best!) ambivalent feelings about dikk and the men they're attached to. They may love getting pounded out, but have low-grade contempt for men in general. I don't want to call nobody out cuz some of them I fw, but there's brehettes who, if you really clock what they be saying, be letting it slip.
I don't know if yall know this, but all that 'nikkas ain't shyt' talk that bw engage in be undergirded by some truly terrible shyt. Those experiences help create what yall call 'the sisterhood.' There's certain levels of... we'll say 'comradery' that I cant even access, because I lack those experiences.
