Why do women need sex?

Seriously, have you ever thought of why women need sex? I know it is not a topic many of us are comfrotable with. But face it, most women need sex. Why? Simply because they wanna feel attractive. Having their partners making a move on them makes them feel attactive, hot and confident. But usually men don't see it that way. We only get it when they really want it. And that makes us feel unattractive, which makes us really hurt and upset sometimes. Especially when they say that others gals are hotter and prettier... *_*

But will they ever understand? I doubt so.
