It's not new, you know...

This is from 1988.

Left hand side wall, halfway up.
Again, manhood themes abound.

And now for something completely...well, alright, no...

Look at the bucket. To the immediate left you'll find the E. Up, left is the S. The X is hidden within the initial spurt of water(?). Big manhood themes going on here.
And when you thought that was it, there's a S-E-X in the cat. I reckon he's male. Maybe two. Definitely two.
G-E-N-I-U-S.

P.S Hang on, I've spotted another.

Edit: There's four in the water, all running diagonally parallel to each other.
Did I say G-E-N-I-U-S?

Volkswagen again, the cheeky monkeys

Two of them, one in the bright white light and one in the low clouds.
Where's the scarecrow pointing to? Can't see it myself.
And all for an off-roader, eh?

Volkswagen again. The Eos.

The actual car, the Eos, isn't actually pictured.
Wait, what make is the car on the left? Look up. What's written on the wall?

There's no actual car, but it's still Volkswagen

Bottom of the white ripples, find the S, look downwards.

Back to the Beetle

Why has the frog's tongue got a shadow?
To divert the viewer away from the X. The S and the E become more obvious after that.
One could also argue that there is at least one, if not two S-E-Xes in the line of clouds.

It's not just Volkswagen

Audi do it just as well.

It's in the engine.

Getting the picture?

Let's have a competition to see how many times we can put S-E-X in a single advert, shall we?

There's one directly above the car, another is to the right hand side, there's another top left reading downwards, the most obvious to me is below the "love is the bug" message. The S goes through the "o" of "love". There's probably more. Have fun!

S-E-X is everywhere (3)

Different car (still Volkswagen, though).

It's a black car. So what's the white doing there?
That's the S, the grille is the E and the middle of the VW badge is the X.
Coincidence?

S-E-X is everywhere (2)

Same car, same idea.

The first S-E-X is obvious, but there is another directly above it.

S-E-X is everywhere

Let's start off with a classic.

It's in the clouds.

The X naturally points to the car, the words and the birds distract the viewer from looking deeper.
