There’s definitely a problem if you’ve had that many sexual partners before you even reach 18. That is not the norm. There’s a difference between having a lot of sex and straight up being reckless.

Just from a health perspective, I highly doubt all those people were tested for STIs, or that she was being tested in between her different partners. Also, I’m betting she wasn’t disclosing her unusually high number of sexual interactions with other partners, which put them at risk of catching something. If I knew a someone had multiple interactions with different partners within the last several days, I’m definitely out, cuz I’m not risking catching something.
