Has anyone else noticed how flagrant girls are becoming about showing off sexual relations? What do you attribute this to?

I feel like this is a projection of their own insecurities about seeing a guy having fun without them, so they post it on SnapChat or Instagram to "show" other people how much fun they're having. It feels like girls these days lack the proper guidance by strong (empasis on this) men, so they do what applies to them, by trying to make men or other women jealous. This happened to me recently. She basically told me how she was with guys of another country and how passionate they were. I just laughed and wrote her off as a common slut. It's good that it's so easy to catch sluts these days... but..

It's just kinda sickening to see it in girls who I know on a personal level. One of my friend's sister, every week, alludes to either getting intoxicated or spending time with males. Her dad is weak and her mom is a "strong woman" who's other husband left her. Her brother, although I love him, isn't much of a leader and his sister lives in an apartment with her friend so she can basically do what the fuck she wants.

In the overall picture, it's not good for woman to grow up in the US society. It breeds narcissism and pleasure at all costs. While this is good for filtering out sluts, it's bad for overall quality of women still around.

Any thoughts on why this is so prevelant these days?
