Any ultrasound techs in here?

We know it's a boy, just wanted clarification of what we're looking at because of course family and friends are confused and keep asking if that little ball is the ballsac. I'm pretty sure it's his penis and then the outline of the sac is somewhat distinguishable under that (what I drew around in the yellow). Does that seem accurate? (I would have asked the ultrasound tech but she was going through everything so quickly that I barely knew what I was looking at before she moved on to the next area.)
