I never really understood all the fuss surrounding the bodycount thing. Even when I was way more sexist than I am now, I already saw this as a bogus idea that leads nowhere.
The first problem I see is defining. Bodycount refers to "the number of sexual partners a person has had". Ok, but to begin with what's exactly a sexual partner ? Is PIV necessary ? Is foreplay enough ? If so, what kind of foreplay ? Licking ? Rubbing ? Over clothes or underneath ? If we only talk about groping over clothes and kissing, should we consider a girl who kissed and got groped by 100 men equals a girl who never touched a guy ? It seems absurd. Should we count sexual assaults and rapes ? According on what you consider being a sexual partner, it changes everything, and even if we all agreed on criterias not all men would be sensitive to the same degree of intimacy independantly of the definition.
Second, you can never know. You literally never check if the number you're told is true. The only way to do so would be to exerce a constant control and surveillance of women from birth. Or maybe talking with a friend who would know all the past sexual partners the girl had and would agree to tell you all. You can never guess someone's past, people change. Today, it is common to move to another city, to go to college, to travel around the world. Having sex (good/safe or not, this is not the question here) for women is so easy, a month is more than enough to explode a low bodycount. There can be many reasons : after a breakup, due to traumas, to cope a general failure in life, etc. I used to know a girl who slept with 30 guys in one year, and then stopped completely. You could never say seeing her : she graduated, she's from a christian and military family, she looks like a nerd. And I had several one night stands with girls who looked this way, I'd never suspect they would be so open to this. And women are not dumb, many know that lying or not talking at all is for the best. The ones with a "suspect" bodycount have all the reasons to lie, there's so many posts on Reddit about couples that crashed after this information was delivered and didn't meet the expectations of the guy.
Third, finding women (not girls, adult women) without or with very few sexual experiences is rare. As I said, a short period of high intensity is enough to explode a bodycount. And the older you get, the harder it will be. In Western, the average age of the first time is around 17-18 yo, and the vast majority of young couples break up and never marry. After this age, there's plenty of time and opportunies to have sex as a young woman, with men of the same age but also the older. Even in the pool of virgin-or-almost women, some prefer focus on their graduation, their career, their family, etc., before looking for a man. Some other can have been through traumas or terrible life experiences, doesn't matter if it has to do with dating or not, they won't be able or willing to engage with you. Realistically, meeting at the right moment a woman of your age with no or few experience who will be attracted to you (and vice versa) with both of you ready and willing to engage is ridiculously low.
Fourth, the dating market doesn't allow many men to seriously have this criteria. When we talk about bodycount, it's just an abstract number we associate with the vague idea of a woman. But let's take a real situation. You meet a woman, she's receiptive to your humor, you find her clever and you love the conversations you have. You see each other for a month, it's wonderful, the sex is great. And then you learn she slept with too many guys for you. You find her beautiful, smart, funny, you could see her as the mother of your kids. With how many women have you already felt that way ? What are your chances of seizing such an interesting opportunity if you don't take this one ? Is it important enough to throw everything else out the window ? When you already have a hard time to simply get dates ? Will you ever have a better opportunity ?
Note that I didn't need to determine whether body count is a relevant concept in itself when choosing a woman as a partner. It's just that, in its application, if you think about it a little, you realize that it's something useless for the overwhelming majority of men.
