So, you're undies will tell perspective partners what position you'd like to night?

Because some of those look a bit ambitious...

Seriously. I am a Taurus and that one looks....like it would work best as an action shot of the person on the bottom collapsing to the floor. Possibly dead.
I am. :(

Sadly, EVERY time I see the "zodiac sex positions", that one is ALWAYS mine. I've given up.
What era was this out off interest? The 60s? She doesn't look that 60s, but the concept does.
This is a lot of responsibility for a lover! You have to be schooled in all 12 of the zodiac signs to know what your woman wants in bed that night? Well, I guess back in the early 70s a man was more likely to know; especially those reading a magazine that would have such an ad. The neighbor Larry on Three's Company comes to mind.

Those panties don't look very "X" to me - lol.
What's the deal with Libra? Who's who? Is that a lamp in the background?
I feel sorry for the Libra guy. Unless the woman's reaching around to manually attend to things, it looks like she's having her fun and leaving him out of it. All the positions at least look mutual, except for that one.
They're called Zodiac "panties" but they have a men's version? What exactly are those? And how is one supposed to know what they look like without some sort of picture? I'm guessing they didn't sell a lot of the men's line.
Oh, so that's why everyone always asks, "Hey baby, what's your sign?"

Ba-Zing!
Forget the sex panties; I'm trying to figure out who thought the uni-boob pose would be a selling point.
