It's a difficult one. Before I was like a higher count its pointless, although it would be hypocritical of me. However, one thing for sure is women with higher counts cannot really pair bond and have some sort of trauma, because lets face it, not all sexual experiences for them will be great and at some point they will run into multiple horrid experiences.
I think now, if you both get along and have trust it is ok. Idealistically, it would be easier to just find a woman that does not have a "higher" count as the "baggage" they carry would be far less. I would not say body count matters when spending money on dates or too take her seriously. Me, I would take her whole character into consideration. Lets face it, unless you are going to different countries to order young women in or you catch a woman in uni who is still naive, odds are the woman has gotten around a bit. How do you even define a high body count? Before when I was younger, I thought 10 was too high 
. Personally I would not really ask a womans count anymore, I would just observe how she acts. I realised that eventually, if the woman likes you....she will tell you everything of her own accord anyway.
Why would anyone ask that question? I guess we are assuming he means cock count?
In my late teens early 20,s I dated a teen who had a body made for sin and loved using it, never asked the question and neither of us were faithful, but where truthful, her parents made us split when she went to Uni, I met a virgin stunner, but the first relationship never ended, the virgin felt her a threat and got pregnant, I did the decent thing and have always had a little regret, and it lasted only a short time.
Never found the level of trust and communication I had with the first one again in my life, we never rowed in 4 years, 2 years meeting only when we could, the child ended it, I met her in a shop some years later, she was with a now quite famous band member and planning to marry, but the look of regret on her face, and mine too, said it all.
I did ask if she wanted to meet again, the child was with me, I could see it was never going to happen but also the regret that things had not been different.
So the answer to the question is truth and trust outweighs everything, judging someone by the amount of sexual partners is shallow and weak, if you need to ask the question it says more about you than her IMHO.
