approximately 85% of transwomen choose to keep their penises and use them sexually, and that a large majority of transwomen are attracted to women

I agree that the polls cited are tosh for the reasons you say. But the number who choose to keep their penises and testicles nowadays is more like 95%. And more than a large majority of adult male humans who adopt a trans identity are attracted to women; the overwhelming majority of them are attracted to women.

Many males who identify as trans women today don't just keep their penises and balls, they write texts and give talks in which they proudly boast about their penises and the enormous powers and wondrous, magical properties they believe their penises have. Examples of this genre include Julia Serano's classic "Cocky" from some years ago, and Grace Lavery's newly-published memoir, "Please Miss: A Heartbreaking Work of Staggering Penis."

Re the fact that nearly all adult males who identify as trans today keep their penises and balls: One of the reasons there is such a push to be able to do genital surgeries on male minors before they have reached the age of consent and cognitive maturity is the fact that most full-grown adult males who identify as trans avoid such surgeries like the plague, and understandably so since most adult males enjoy the ability to orgasm and find it vital to their lives. So just as the "gender affirming" medical "care" industry is promoting double mastectomies as a panacea to a target audience that consists entirely of tween and teenage girls and doesn't bother trying to peddle these surgeries as mental health boosters to older women, the gender medicine industry has zeroed in on underage boys who were transed by their parents in childhood like Jazz Jennings, Jackie Green, Trinity Neal and Kim Petras as the main market for "male to female bottom surgeries." Gotta get 'em young, because once they've grown up, these male youths might say no.
