We tend to filter things through our personal experiences. I kind of envy the people who were purely confused or whose first thought was astrology girlfriend.

My honest recommendation is that you calculate your chart, then pick one thing in there that resonates with who you actually are, then emphasize that when the conversation comes up. The charts are long and messy with lots of different meanings mixed in for a reason. Even just between the sun, moon, and ascendant signs you should be able to find one of the three that describes you. If not you can look into the planet / house alignments or even just have the chart made sidereally.

It's a small amount of information to memorize, then you can say,"oh my sun sign is Aires but honestly it's my Libra ascendant that matters most of the time. I'm just always looking to make the world more equal." It'll both satisfy the person you're communicating with while also providing them with a way to conceptualize your personality within their worldview (which is basically the entire point of dating, or even just vetting sexual partners).
