We all know you're plenty of fun, WG!
I know of at least one porn star who loves sounding (Jessie Colter). Although it's more of a hypothetical for me as a cisfemale, after a painful experience with a cytoscope inserted in my urethra to check out my bladder, my inclination would be to protect my (non-existent) junk from such invasion.
But to each their own. I know a writer who made sounding seem hot, and she wasn't writing from experience, just from research. Those of you who do not like kinky, intense stories or Dr. John Watson of BBC's Sherlock depicted as not-entirely mentally healthy should not click the link.
