I've noticed something in women, the more women I have experiences with: there are 2-3 types of women: low libido, normal libido and high libido.
Low and normal libido women make good wives and long term partners because they are less likely to cheat on you in general, they don;t feel the sexual desire of a normal libido woman, let alone that of a high libido one. Just like some of the greatest artists used to castrate themselves, these women can focus on other pleasing and fulfilling aspects of a relationship with a man rather than just the sexual one.
High libido women...are good for some things, bad for some others. They are good for a man who hasn't had much sex and is looking to gain experience, you can explore sex with this type of woman often and in different ways. These women will masturbate regularly and if, like in the article, they do that more than 3-4 times a day, they are entering sexual addict zone.
In my experience, women with lower libido will give sex rather easier than women with high libido cause they don't consider it such an important thing, they don't feel it. Women with higher libido are made to think there is something wrong with them by societal standards and in fact, even biologically, there is: they usually got a higher testosterone level in their genetics, sth that leads in more masculine behaviour like wanting to have sex more, having more "manly" body features (wider jaw, more hair around the sideburn area of the face, generally more masculine behaviour) so this is not very natural at all. These women are acting manlier and you need to understand when you deal with them that (not necessarily), they are more likely to cheat unless what you're offering exceeds the pure pleasure from sex.
Any normal person shouldn't have to have sex all day. There are other, healthy ways to spend your energy other than fornicating like rabbits. If any man or woman feels like doing that, they definitely do have a disorder, be it physical or mental regarding sex and they need to take care of it. If you involve yourself with such a person, protect your feelings and make sure you feel the mostly physically, not much emotionally (I don't see the point in that anyways, but whatever).
