I don’t know how much worse than general nsfw you guys think it is. I don’t think it’s that bad. Sounding is where you insert something into your urethra. Usually it’s a male activity. If you are afraid of penises then maybe don’t look it up. Maybe the simple idea of inserting something down there might make you uncomfortable. Also it’s the name of medical procedures where a doctor inserts something into the urethra so there’s plenty of nurse/doctor imagery if you look it up.
