When you stop busting fat nuts on a daily basis your gonads can develop a life of their own and particularly if you have naturally large low hangers, as you describe, you can feel like you’ve got two live grenades swinging between your legs which range from ‘sensitive’ to ‘achey’ to actually ‘painful’. Hard to believe it but this will settle. So long as you no fap you’re balls are not gonna be there but dead like when you milked them dry day in day out, they’ll likely remain plumper and sensitive but hey man they’re making the seed of life: your body’s letting you know that ensuring you’re taking real good care of them. Oh and finally- men have “live” plump balls rather than the drained prunes of a fapper.
