Serious? Or just being sarcastic?
Have any links to articles that suggest this? Not because I want to dispute you, but because that could potentially be quite valuable for me to learn a bit for.
I have not simply googled this topic, as I am hoping you have a good article that discusses this. Perhaps one that convinced you.
That’s something I REALLY hate about women.
Put it this way, if a girl asks us guys to do something, if we’re interested in her, we will go, even if it’s something we have no interest in doing. It’s the person that matters to us, not the event. Perhaps I’m generalizing, but this is how I feel, and I think it’s how most guys feel.
But women on the other hand, quite often I’ll suggest to girls I know to go out and do something, or come over (not a formal date or anything, just a hang out). Sure, many say yes, but also some say no, without a reason behind it. I often feel okay, she’s not interested in ME, move on.
Yet, sometimes I’ll go back to the same girls and throw out another suggestion at another time, and sometimes they’ll say yes. So again, wtf? It’s as if women don’t care about whether they like you or not, it’s whether or not you are suggesting something they are interested in doing.
Just something that I find a little frusterating. That’s all.
Yes - Tuth is fine when well moderated by socials and IH/IG will round it out very nicely.
Good luck - Fingers crossed! 
The best way to prove this fact to yourself is through empirical data. Begin by selecting a nice-sized sample, say 30 shy girls (n=30). Then one by one, expose them to the cock-out approach method. Even if it happens that the first few are non-responders, by the end of the experiment I promise some verrry interesting things will have happened. 
And have good legal insurance in place! 
And do vary the trial by putting a couple of doughnuts on it! 
I agree, the mixture of cock-hungriness and doughnut-hungriness could really drive these shy girls over the edge!
