Striving to avoid having a stiff physical manifestation in one's genitalia
Although doing so, I'm focusing hard on preventing any form of undesired sensual stimulation below the belt. Through this struggle, I'm determined not succumb to any sort of automatic corporeal manifestation that may come up.
In a conscious attempt to suppress any unwanted biological manifestation, I find myself actively contending to avoid having an overwhelming erection in that region at this particular instance. By way of sheer determination, I work to repress any urges linked to sexual arousal.
