I used to shoot a fair bit, and my state of mind had a massive affect on my shooting ability. If I was in a bad unfocused state of mind, I struggled to shoot pop cans at 20 yards. If I was in the zone, "zenned" out so to speak, I could shoot 3" groups with a .22 at 100 yards... with iron sights. I eventually learned how to drop myself into my "zen" state. It starts with my breathing. Most of the time, we breath without being aware, just automatically doing it without thought. By making myself aware of my breathing, and then focusing on controlling each breath, I slowly reign myself in and "center" myself. Once I've achieved "control" of my body, I then start running through my shooting checklist. Relaxed muscles, properly couched cheek, proper body posture and positioning. Then I line up my sights, zero in on my target, all while maintaining controlled breathing. Once I'm close to lined up, only then does my finger drop to the trigger, making sure it's properly positioned so that the squeeze doesn't cause a misalignment when the round fires. I time my squeeze with the last exhale, a very slight pause, and then CRACK! The shot should surprise me if I've done everything right. I'm not saying I'm an amazing shot, and it's been years since the last time I went shooting, but I knew that if I wanted to I could have done very well in competitions. I'd like to get back into it and see if I ACTUALLY am good enough, but I've other hobbies occupying my funds and time. I'm still learning to achieve my zen in those hobbies.

A couple other "mind controlling body" abilities I've developed, more inline with this subforum, are orgasm suppression and size expansion. They start with controlled breathing like my shooting, but delve more into my "energy" (for lack of a better descriptor), and thus differ a bit.

For the suppression, as I'm quickly approaching or am about to go over the brink, I mentally identify that building ball of energy in my core, that building feeling down in my groin. Once I've got a mental grasp on this, I imagine closing my "hands" around it, like catching a firefly or a dodgeball, and start compressing it in and pushing it back down. It's almost like trying to squeeze a bright intensely vibrating ball of energy into a jar with a too-small opening. If I've successfully got control of it, I can feel my core pushing it back down into my groin, and then the feeling slowly subsides into a dull hum rather than threatening to boil out in an explosion.

As for expanding my size, again I have to identify that source of energy, but this differs in that I'm not trying to suppress it, but instead am trying to harness and direct it out. So I'll feel that energy, less like a ball when I do this but more like a pool or reservoir deep down in the core of my groin, and I'll tap into it, slowly pushing it out into my shaft. This becomes like a guide wire for my muscle contractions in my pelvic floor (similar muscle contractions to kegel exercises for women), which I will use to push my blood outward and into my shaft. I'll feel my shaft get tight, and then stretch out, expanding it beyond it's normal size. Using this technique, I've achieved expansion of close to 1cm more in diameter, and at least 1.25cm in extra length. Might not sound like much, but it makes my fiance go wild eyed and she'll sometimes lose control and claw my back up when I pull this trick out mid-sex. Especially when I pulse it.

Both of these techniques require I start with my breathing exercises for best success, achieving awareness and then control of my body before attempting. Sorry if this is TMI, but I felt it suited the vein of the convo. Btw, I have yet to achieve willed orgasm, but I can use the expansion techniques to stimulate myself into arousal.
