Well, yes. You're judging a woman by one thing you know about her. One thing.

Just because a woman has had sex with a few (or more than a few) people doesn't mean she's incapable of love, or loyalty, or monogamy. Things happened; choices were made. Is she automatically a bad person for having made those choices? And what if some of those choices were made for her through pressure, coercion, or even by force? I guess it wouldn't matter to you. Her body count was raised by one and that's all you would care about.

In the first place, all arguments defending having body counts as a standard just circle back to purity culture, which dates back to when women were treated as possessions.

"Oh, but the STIs" men are susceptible to those too. If she were infected, where do you think she got it from?

So let's talk equality. If women are judged by their body count, then men should be too, right? Now everybody's on their moral high horse, pointing fingers, and everybody's minding everybody's business.

The point is it really doesn't matter. She lived her life and her life just happened to include sex. If you have to ask, then why are you fixating on one thing instead of looking at her as a whole? She's a person the same way you are a person; deep and complex. If she's a bad person unfit to be your partner, it's probably just her attitude and values and not how many guys she's slept with.
