Actually, in countries like the US, Canada and the UK, the majority of guys who "transition" are heterosexual (sexually attracted to women).
In Western countries in the northern hemisphere, most transwomen are straight men like Bruce Caitlyn Jenner.
That’s why for a number of years now, places and events in the Anglophone world billed as for, by or about lesbians - online forums, dating apps, social events, political organizations, arts festivals - have had a considerable number of straight men.
For example, when the Biden administration held an intimate “White House roundtable” for a select group of “Lesbian Leaders” to commemorate Lesbian Day of Visibility in 2022, two of the seven “Lesbian Leaders” listed by name in the WH press release were straight men.
In the photo of the event shown in the X post below, White House press secretary Karine Jean-Pierre, who is a bona fide lesbian, is flanked by two straight men who now claim to be lesbians: Charlotte Clymer, who went by Charles/Chuck until his early 30s and as such developed a reputation for being a “creepy male feminist” with a penchant for verbally abusing women; and Biden Assistant Secretary for Health Rachel Levine, who went by his birth name Richard until age 53.
In the press release for this event supposedly honoring and celebrating lesbians, the White House added insult to injury by naming Levine as one of the three “Lesbian Leaders” in attendance who had earned the further distinction of being
the first out lesbians to hold their position, including: Ambassador Chantale Wong, Director of the Asian Development Bank, who is the first out lesbian to be confirmed by the U.S. Senate to an ambassador post; Admiral Rachel Levine, Assistant Secretary for Health, who is a lesbian and the first openly transgender woman to achieve the rank the four-star admiral in any of the country’s uniformed services; White House Deputy Press Secretary Karine Jean-Pierre
