I'm a male, my chromosomes are XY.

When you're born, you're given your amount and kind of chromosomes.

And hence, your sex.

Your example was irrelevant.

You were tested at birth?

When you're born, you're given your amount and kind of chromosomes.

Can I get a source I vaugely remember that they don't test it

My cock is your source.

Literally.

Im pretty sure you can have a cock and have other chromosomes

Rare

But I think possible

I'm not XYY nor XYY.

If I were, I would know.

Have you tested?

When you're born, you're given your amount and kind of chromosomes.

Or are you assuming

When you're born, you're given your amount and kind of chromosomes.

When you're born, you're given your amount and kind of chromosomes.

Are you identifying

When you're born, you're given your amount and kind of chromosomes.

When you're born, you're given your amount and kind of chromosomes.

Source please

I may be wrong

My COCK is your source.

But I don't think they test you at birth

Depends on your country tbh.

But they tested me.

I don't think Ugandans test your chromosomes.

Can I get a source on that ur euro "country" tests?

Yes, that's why you have google.

Im willing to be convinced that countries test

Where do you live

USA.

New York.

What does it matter if they test it though?

Well if they didn't test

And you are assuming that it is xy

Then the reason you are a guy for you personally

Is because you identify as such

Anything different than XY is noticeable, genetically and physically.
