Re: Could it really be true?
It's hard to say without any stories of some of your experiences with these girls. I can say that it is possible. If you really separate yourself from some of the typical guys, and you go through the phases of attraction correctly, than she will be comfortable enough in trying out new things with you.
Others, as you have said, are just plain bs. They say it to try to make themselves look like less of sluts and more like ladies. With these kinds of girls, you should treat them as they want to be treated. Like David X says, treat the sluts like ladies, and the ladies like sluts.
Unfortunately, I can't really give thorough advice on this matter without some extra detail. Could you please post some of your stories and interactions with these women? Don't be afraid to exclude detail
