Had my bladder video a few months ago. Was very uncomfortable when lens went through prostate, but other than that, no problems. I sound a lot but obviously nothing as large as that lens.
I've never understood the practice of sounding. Unfortunately I have had the need to have my bladder videoed a few times which I found very uncomfortable. So excuse my confusion.
O yes, I get right into my prostate. M'mmm it feels awesome. I attached my E-stim to my rosebud sound the other night with the help of a conductive but plug.
