Striving to refrain from getting a rigid physical manifestation inside one's lower parts
Even though attempting it, I'm focusing strongly on avoiding any form of unwelcome sensual stimulation underneath the lower half. Via this attempt, I am determined never succumb to the slightest involuntary physical reaction that may occur.
In an effort to control any unwanted physiological reaction, I find myself actively contending to avoid having an overwhelming erection down there during this particular time. Through sheer willpower, I attempt to repress any impulses relating to sexual stimulation.
