Working hard to avoid having a rigid swelling within one's private parts
Although attempting it, I am putting my mind intensely on preventing any kind of unwelcome erotic excitement underneath the midsection. With this struggle, I am resolved never succumb to any uncontrolled physical reaction that may come up.
In a bid to curb any unintended biological reaction, I am actively struggling to abstain from having an involuntary boner in while this given time. By means of sheer self-control, I work to repress any desires relating to sexual excitement.
