Making an effort to avoid having a erect reaction inside one's private parts
Even though attempting it, I am concentrating vigorously on stopping any variety of undesired sexual arousal underneath the lower half. By this effort, I'm committed never give in to whatever uncontrolled physical response that could come up.
In an effort to suppress any unintended bodily response, I find myself actively contending to abstain from having an intense erection down there at this particular instance. By way of sheer self-control, I strive to repress any impulses associated with sexual stimulation.
