well... first off...I think if you get better leverage then you can hit yourself harder in the nuts... BUT, if you wanted help with iMCF and not making sure you can't procreate then I can try and help (as well as telling you to go to the yoshi forums and checking out a few things there about the move...neo put up a tutorial and everything.. I think its on Youtube as well).
Okay so...first off...the right hand. Put your upper left corner of your thumb onto the middle of the X button (a little more to the upper left of the X button is better than just simply dead center). Now its more of a FLICK than a SLIDE in my opinion. As they say "its all in the wrist"... so you should be flicking your wrist to the upper right part of your controller while at the same time flicking your thumb so that it STOPS hitting the X button and STARTS hitting the Y button. If you did the motion correctly the tip of your thumb should almost (or actually touching works too) your pointer finger. A good way to practice to make sure you are doing this motion correctly is to go to training and pick setsuka. Crouch with her and press in the 3 direction while still crouching. Holding the 3 button, try and do your slide motion with your right hand. If you are doing it correctly you should be doing her Just umbrella. If you are not getting her just umbrella then you won't be able to be getting iMCF.
Now that you have the timing down on the right hand, go to the left hand. This is simply pressing down at the same time as starting your motion. A good way for me to do this i've seen is to have your thumb in a position so the tip of your thumb is not touching the stick at all and instead its more of the middle of it thats being used to move the stick. This will be a flicking motion downwards with your left thumb. Don't worry as much about the speed of the downward movement as much as making sure you are hitting the 2 position, because the way that the controller of xbox and ps3 are set up, sometimes what FEELS like a 2 can be more like a 2.5 and will sometimes be registered as a 3...kinda bitch...i know.
Now that you have your left and right hands all good..combine..which is just puttign the timing down so you start doing both flicks at the same time. Now jsut sit there doing it again and again and again and you'll be ALLL good. Also...another way to get it in a match better.... is to start by giving your guy a little step forward...so tap towards the opponent, then do your imcf. This will let your guy do a little step forwards at which point you will pull out your dick punch (kinda funny how you dick punched yourself instead of your opponent btw...lol) and a lot of the time the quick step and having not attacked will land you a counter hit on anopponent that is trying to hit you while you are running towards them. And the move is even EASIEr to get off atack buffers such as 6A of BB.
I play on xbox 360, but the method works the same with a PS3 controller from what I've personally noticed (although I do it better on xbox simply cuz its the system I'm used to I guess). So have fun with your dick punch...and try not to iMCF yourself in the nuts again....if it causes crumple stun on a FIGHTING CHICK? imagine what it must be doing to some guy drinking a redbull and playing a video game :P
