Assuming you are a man you seem to not think highly of your own gender, as if a man has no choice but to have sex with so-called "liberated" women. That is affirming what many of them say: that men have no control. I mean, if these kind of women are not what you want, then leave them alone. If enough men take that initiative I think a lot of women might rethink their positions.

That isn't even close to what I said or meant. What I'm saying is that if one guy keeps his pants zipped and she goes off to zonk somebody else, the problem is her's, not the guy who keeps his pants zipped, or men in general. The only possible way for her to keep out of trouble is a total lack of availability of partners. The rational approach is not to need to completely eliminate partner availability, but for them to start using some morality and character.
Let me put it to you in language we can all understand. Women are giving their bodies and emotions to characters they don't know well enought to loan a twenty dollar bill, then complaining about the consequences. I could tie a penis to that fireplug I see out near the street and a large percentage of contemporary women would go out and hump it, then complain bitterly afterwards about how abused they were by men. That isn't a man problem.
