The concept of identifying as the opposite sex meaning that you are in fact the opposite sex has profound implications (being completely nonsensical, notwithstanding).
It is certainly a well trodden path in terms of the ideology.
And will earn you the title of terf, transphobe and bigot, if you disagree. Not for genuine transsexuals like Miranda Yardley, (but unfortunately they are now few and far between.)
It has led to the concept of the cotton ceiling. A play on glass ceiling and representing the underwear of women, particularly lesbians (they can't really pick on straight women, because they identify as women themselves. So that would make a straight woman a 'lesbian').
The cotton ceiling is something for men who identify as women to 'break through' to access sex.
So despite having a penis, the body is female and should always be viewed as such, specifically in terms of lesbians who will be considered transphobic for not wanting sex with a man.
This is part of an email exchange between a lesbian and a transwoman.
Trans women are female. When our female-ness and womanhood is denied, as you keep doing repeatedly, that is transphobic and transmisogynist. As I said earlier, all people’s desires are influenced by an intersection of cultural messages that determine those desires. Cultural messages that code trans women’s bodies as male are transphobic, and those messages influence people’s desires. So cis queer women who are attracted to other queer women may not view trans women as viable sexual partners because they have internalized the message that trans women are somehow male.
Being male is a cultural code, not a biological fact.
