Why do the heartless female sluts get all the praise?

Can someone explain to me why the heartless female sluts get all the praise for having with so many men? I just don't get it. Why are they being upheld for having with so many people and breaking hearts like it's something to be proud of; while the girls who want to be in monogamous relationships get labeled as the too nice, or boring ones. Then you see the sluts out ping std's and getting abortions as easy as changing there birth control patch (if they take one). I'm all for womens rights but how does this get count as women's rights? There are double standards for a reason and that is a good reason for them. Others opinions, comments, answers appreciated...
