I tried to write on a plane with the code

#declare text1 =
    text {
    ttf "timrom.ttf" "POV-RAY 3.0" 1, 0
    pigment { Red }
  }


plane{<0,-10,-2>,4
    texture{
        pigment{
            object{text1}
        }
    }
}

but it does not give the result I want.

1. The text does not appear (probably appears somewhere, which is not visible).
2. I cannot apply color to the pigment of the plane.

What is the correct way to put a sex on a plane?

Other than your typo on the last line.

The text object needs to be called separately and it cannot be used as a 
texture. So you need the plane and text1.
You might want to think of using an image map with writing on it for the 
plane although a thin box might give better results as in PovRay planes 
stretch to infinity.
The text object is a 3D object and has depth as well as height and width.

A couple of things.

Careful with that translator.  ;)
You need to use a pigment_pattern to make the plane patterned with the text.
See how I calculated the string length and used that to scale the repeat warp.
Then you need a color map to pigment the text (which is now formally the parts
of the plane corresponding to the 'inside' of the object pattern), and the plane
(which is now formally the rest of the plane corresponding to the 'outside' of
the object pattern)

The text needs to be scaled to be thick in the z direction, and then shifted
back to center it.
I haven't gotten around to implementing WP's suggestion to infinitely scale it
with a function.

This is also very quick just to show you the basics - you'll probably want to
align the pigment pattern with the plane so the text doesn't look like Star Wars
or Dick Balaska's epic 30-year movie intro.

My unconscious mind had a subtle way of making a typo :D

Sorry about that! :p

I can only hope you're not missing out on the fun part - otherwise you'd
certainly be doing _it_ wrong ;)

(And by "it" I obviously mean using POV-Ray ;))

Thanks! You couldn't explain it clearer.

Two rules to follow please:

(1) If posting such HTML addresses for fun, please make sure they DO NOT
actually work.

(2) If replying to such HTML addresses that DO work, absolutely
positively DO NOT QUOTE them.

Now I have to nuke two messages instead of just one.
