When Did Women Become Men?

I've been blessed with a handful of beautiful, independent, confident women to call friends. I can tell these girls anything, and they never judge me. We talk about everything from education, religion, motherhood, politics, music, to sex. Ahhh, sex. How often we broach this topic. During one of our many explicit convo's I had a thought. It hasn't always been this way. The belief used to be that after a woman engages in sexual activity, she gets attached. She becomes clingy and is automatically expecting more. This belief seems to have changed. Maybe not worldwide, but definitely in my world. So I pose this question: When did women become men?

The women I know (myself included) approach most sexual relationships like men. They are completely capable of being in sexual relationships without "catching feelings". Some even prefer it this way. So when did this change? I can't even pinpoint when the change occurred for myself, let alone others. I do know that times have quite obviously changed. Women are not as commonly thought of as "hoes" if they enjoy sex without attachments. This is a change for the better. Every consenting adult should be sexually liberated. Women should not be ashamed to enjoy or seek sex. Everybody needs a little "sex therapy". And on that note.....
