I guess it was my dad's preference. It was never discussed. Yeah, it was awkward and embarrassing, especially at that age when you are very self conscious about your body. The exam in all honestly wasnt too bad though. I would have my shirt off and be lying down on the table wearing my shorts and underwear. The doctor was on my left, and my dad on my right. The table was pretty high and I was about eye level with my dad. The doctor would examine my upper abd, then he would undo my belt, button, and zipper himself. He would spread the opening of my shorts, and lift up the lining of my briefs to continue his exam onto my lower abdomen. I always knew what was coming, and I would have a full hard-on. This means as soon as he lifted up the waistband of my briefs, my dick greeted him pointing straight at his face. He would palpate my lower abd while brushing against my penis a few times, and then say something like "Okay, we are going to have a look all the way down here." With that, he would grab my penis and examine all aspects of it. Starting with the head, he used his thumbs to spread open the urethral meatus. Then he would examine the head, followed by the shaft. He moved my penis left, right, up, and down to check it from all sides. This was all done sorta inside my underwear and with him pulling the underwear down slightly and lifting my penis up. He would then move down to my testicles by putting his hands further down my underwear. I remember looking up and seeing his palm resting on the top side of my erection while his fingers are playing with my testicles. After he had felt enough, he would retract his hands and redo my shorts. The exam was over and he would give a report to my dad.
