We are talking about a whale and then you give me dolphin pron?
What am I supposed to learn from the video? I can't see the internal structure in that video, but I am supposed to conclude that dolphins don't use or need their pelvic girdle? Why are all their sexual organs connected to it then?

I gave you dolphin as example because you had claimed that whales must use their pelvic limb remnants for sexual function since their penises are huge - hello!!! dolphins and porpoises are kind of related to whales, don't you think so?? And it is so funny how in the same article where you took your diagram there is ventrodorsal view of it with arrows pointing to tibia and femur. You know what tibia and femur is right?
And to answer you last question - because we are all mammals and had common ancestor. What do you think human penis is attached to? Bull? dog? Horse?
See and compare some animals genital systems for example. Striking similarities due to common ancestor.
