LOCK
The lock is a discrete, terminal state of ejaculation energy in which the orgasm has settled in the tip of the penis and blocked the way down, so the sensation can no longer be deescalated even though no ejaculation or fluid is moving. It could potentially be a hormonal release or overexcitement of local nerves. When you encounter the lock, treat it like the ramp: loosen up, do not flex the PC muscle (but maintain general lower-pelvis tension), keep breathing, and dissipate the energy until the lock is released. One nuance is that you will likely not be able to flex your PC muscle at all but instead will dissipate until your penis has softened and all the risk of the lock is gone. The only danger during the dissipation is if you lose focus and allow the energy to reemerge toward the tip. This is due to the long time it takes to dissipate the energy, during which it’s too easy to slip. An apparent cooldown can be deceptive: wait until long after the sensation is gone before testing a flex, since flexing too soon can restore the lock. Focus on pushing the energy into the brain if you are sensing a potential escalation.
