Not so sure : oscillating boobs generate a great loss of energy and are thus a disadvantage for running, when you are a girl. Same thing (although a bit less) for oscillating penis when you’re a boy. However, running bottomless for a girl may bring some advantage : greater freedom for legs, leading to greater steps. On condition that her vulva is carefully epilated, to reduce (h)air friction…
I can say two things from experience:
1: Full range of motion
2: You want to strap boobs in a sports-bra and flapping penis while running does hurt. I’d fix the penis to the belly with a cord.
Isn’t the guy who drew this a confirmed pedophile?

I was going to say something similar but you beat me to it. In this case, however, the jiggle factor shouldn’t be a problem. 😉
