In the main comic storylines, Aquaman is not gay. However, there might be alternate universes or special editions where his character could be portrayed differently, but that's not the norm.
The story of Aquaman involves his struggle to find his place in two different worlds. He faces challenges from both human and Atlantean enemies as he strives to unite the two and bring peace. His powers and connection to the ocean play a crucial role in his adventures.
One of the great Aquaman novels is 'Aquaman: Andromeda'. It really delves into Aquaman's connection with the underwater world and his role as a hero. Another good one could be 'Aquaman: The Trench'. It shows his adventures against the menacing Trench creatures.
