I always thought there was a shaming stigma attached to women who only want sex. In the US you often hear those women being called sluts or whores. At least that was how it was offline, I'm not so sure about online or dating sites. Or if that stigma is still attached. Based on some of the comments I've heard in the forums, it seems to be.
As far as men were concerned, those that were only looking for sex were considered to be "sowing their oats". It was considered normal for the young guys to sow their oats, but young women were supposed to be ladylike. Though I'm not sure who the young men were supposed to have sex with if it was inappropriate for young women to do so, haha.
I believe if a woman wants to seek only sex, that is her business. There is no right or wrong to it, unless she's using sex to hurt others, imo.
Women are still stigmatized by men who are truly looking for love, and many others who respect the gift of sex and it's true purpose of being given to mankind, and that purpose is to be shared between husband and wife, not just man and woman. Sex is spiritual, more than just physical, and every time one has sex with a person, you've joined yourself to that person spiritually for life. That is called a soul tie, which is why sex is only to be shared between a man and woman who vow to be in a covenant agreement before God, and not let no man put asunder, what God has joined together.
