To have lived as the opposite sex....

[musicalfrog]

Would be to have been born that sex and treated accordingly since that day.

There is no other way. So it's not really possible is it.

That ought to be conceived , not born.

Well, quite.
It isn’t possible to live as the opposite sex.
It is a meaningless term.

The nearest thing to a definition of ' living as the opposite sex' that I have come across is having bills in a feminine-coded name or having people use opposite sex pronouns when referring to you.

In other words, a person is living as the opposite sex if they can persuade other people to join in with their LARPing.

True, @TheSandgroper

@JellySaurus it's like the crust of the earth compared to all the other layers. Or the length of time modern humans have been on earth compared to the time preceding them.

Oh hang on that's science. These people don't understand that. 🤔

The only way to get close to living as the opposite sex is to force every single person around you to collude in a lie, as you play pretend.
You either lie to people's face, or expect them to lie on your behalf when they know the truth.
I wouldn't see that as "being your true/whole self" !

It's not possible to live as the opposite sex.

But apparently a fake name on a utility bill is all that is required.

Nonsense isn't it.
