Confused by my ultrasound...

Ok, I have one 14 yr old daughter and have been pregnant with 3 boys (one is an angel in heaven) in the last 4 years, so the boy thing isn't new to me. I am pregnant again, now almost 24 weeks. When I was 14 weeks I had an ultrasound and we all saw girl, she said maybe boy but the cord was in the way so we weren't sure. At 19 weeks I had another one, told boy. I am in serious denial because I just don't believe it. And I'm very happy to have a well endowed child, but his little member is as big as his legs in this picture! I have NEVER seen an ultrasound like this. Then compared to where his butt is, it just looks weird. Am I crazy?? I know right away it's a boy no doubt, but then looking at it....I don't know just so different! And boys don't have testicles until they are 27 weeks, so how could his be so prominent??
