We won't, because vaginas have variable tightness and malleability, while Cocks are pretty rigid in their size (Pun intended).

Plus, cocks are easier to measure. vaginas would be VERY hard to properly make a silicone mould out of. 

Jennifer Lawrence equals one woman. If we're going that route, you can find numerous instances of disgustingly sexist men.

You know, that's not excactly true. They do adapt to "smaller" size, but when it's someone who's really tight in question, it can really feel like someone tries to rip your dick off and bend it in the middle. What it feels depends also on how deep can you get. 

Wasn't this about women's hypocrisy? But that is typical female behaviour: you bitch about being judged by "something", but the next thing to do, is judge someone else by the same criteria. Or the opposite: first you judge people based on something, and when people follow your example, you start bitching that "this shouldn't be done".

In a way this is because of the passive-aggressive behaviour of women, where you go up in social status by badmouthing others. Typically the women start badmouthing other women by calling them fat whores or anything like that, then the guys, in hopes of getting laid, follow the example. When it is you being the target, you try to change the "rules" of the game to favour you to go up in hierarchy.

This is actually very interesting social game. Women always try to have a "mass" behind them. The more guys you have on the "friend zone", the better your social status, then again, they can turn their back on you with a snap of fingers, when it favours them.
