While I’ve never had a scrotal ultrasound, I would love it for the experience.
The only ultrasounds I’ve had done were a renal ultrasound and a trans-rectal ultrasound.
The trans-rectal ultrasound was amazing both times I had it done. It’s a big wand like probe that is basically several inches long and fairly thick in diameter. The end of the probe is egg like , so when it penetrates the hole, you really feel that insertion!! The best part is they move it all around, in and out and around the rectum and even go deep to get a reading on the prostate. I love it!!! Both times it was done by a female tech. Younger tech was super nice, very comforting and only had me pull down my pants and underwear to my knees. The older lady tech was also quite nice but seemed old school.
She asked me to remove my pants and underwear completely and gave me a towel to cover up while I waited for her to come back in.
She came in and I assumed the position, laying on my side with knees to chest, I handed her the towel and we began. My penis was pushed through my legs and completely visible to her the whole time, yes fully erect! I loved the embarrassment of that whole situation!!!
