Yes the ocean has a feminine nature. Tranquil one moment then wham heaving the next, warm one day, freezing the next. Bright bluegreen, then grey and ominous. Playful then deadly.Ultimately though nurturing and a sustainer of life. This obviously plays into the scenario of being reborn when spat out of a tube. There is nothing like setting up a barrell, being covered by the lip watching it curve and thunder but seeing the way out and finally being released back in to the "real" world.
I have surfed many times with dolphins, sometimes in the wall of the wave, sometimes flipping and spinning around me and on a few occassions I have released my board and swum with them and even patted them. They are very curious and appear to have an affinity with humans. Science has claimed that their sonar can see a placenta in a pregnant woman, so that could be a link.
