It makes me groan too, but bear with me.

What's important is that the vast majority of women believe that the arbitrary position of constellations and planets hold some power and meaning in their lives when it comes to people's personality and their relationships. There's something about the metaphysical and mystical irrationality of it all that they can't resist. Love it or hate it, this confirmation bias snake oil has persisted and matured for millennia and I don't see it dissipating any time soon.

If you plan to interact with women with the intention of escalating towards intercourse, having some surface knowledge of this BS can be handy. Early on while talking, she might ask you your birthday which is a simple means to determine what your main "sign" is. Once she knows your main sign, you are going to be viewed through that filter. If you know the more positive aspects of said sign you can emphasize its more alluring qualities to better whisk her away in some enchanted bliss. Maybe your sign is known to be good in bed, is mysterious, is adventurous, you catch my drift. If none of this is explicitly brought up, she's probably churning her hamster trying to figure out what astrological box to put you in.

Conversely, you can learn her sign and hear from the source in what respects she sees herself fitting the mold. This is all just an icebreaker at the end of the day. Sure, you are stepping into their frame, but there's no reason to be as fully consumed by the bullshit as they are. Just a little token tip of the hat can go a long way in comforting them, setting them at ease since you "understand" and are somewhat familiar with the opaque contours of their whimsical frames.

Granted, one can also go the hard ass route, call them on the BS and make Astrology a point of contention to get them hot and bothered. Nothing riles up the emotions like a meaningless argument. It's a risky card, you're not going to change their view, but hey, if you can see yourself slapping their booty while calling them an "insert sign" cunt, then why not?

If in some rarity you have stumbled across a woman who rejects astrological validity outright, she is probably of a higher mental caliber than her peers.

I hope this has provided some overlooked but nonetheless ubiquitous insight

Cheers!
