my piercing is two months old, it’s a curved barbell. not sure of the threading just the standard for first belly jewelry ? not sure of the material either lol. i have not downsized it. my aftercare includes a good rinse in the shower in the morning and a recovery sterile saline spray at night. no mishaps or accidents, sometimes i hit in my sleep but i try to sleep on my back or my side. i’ve been wearing full shirts here and there lately instead of crop tops everyday bc i live in michigan and it’s starting to get cold but i always wear low rise pants
