I had to have a testicle ultrasound to rule out any problems when we were trying to get pregnant. I was in a dark room with a female nurse with just my sac showing. I had a drape covering my legs and stomach. Then she coated me with cold gel for the wand which she rubbed all over my sac. Sometimes pushing hard enough that it hurt like getting hit in the groin. It seemed like forever and I was hoping not to get an erection from the touching, etc. When she was finally done, she handed my a tissue to wipe off all of the gel and left the room. I got off of the table and tried to clean off and noticed that the exam table had stirrups and thought it would have been fun to be in that position while she did the exam. I went home and masterbated to the thought of what just happened.
