Butt Cheek Electrolysis

Hi there, does anybody have experience with getting electrolysis on their butt cheeks? I’m going in to get large volume done + numbing… hoping to clear it in 1-2 sessions… anybody have experience with this body part and how long it took them to achieve really smoothe hairless skin for the most part? I know everyone’s mileage varies… the electrologists I’m working with are pretty talented…
