Can anyone see...well...it?

I am probably just being crazy. We got our 20 week ultrasound done and were told we are having a little boy. We are very excited! At that time I could see it. We got another ultrasound at 23 weeks and we were told again we were having a boy. But I dont see it this time. I can tell we are looking between his legs and I can see what looks to me like a hand. Im sure they told us right and we are having a boy. I just dont see it. Can anyone explain to me what I am looking at?
