If you're going to kick yourself in the balls, presumably you kick them both at the same time with your favored leg, making use of the increased precision of that leg's motor skills and balancing as needed on the other. You're not going to jump in the air and try to kick each individual testicle with both legs at the same time. So it's not surprising that there is outsized damage to the lowest hanging testicle due to undue force in an attempt to get both in a single kick. Another option would have been to kick one's balls "Tai chi style," moving the foot ever so slowly toward the groin. But if you're not used to doing that you're just as likely to strain a muscle or trip.
