it would be interesting to have diana be interested in bruce, like in the cartoons, but she has to break through his shell.
she likes him superficially but also because of his values and sacrifices and heroic ambition. she attempts to court him but he turns her down respectfully, but after an onslaught of "hints" he finally has some real talk with her. she should move on, he says. he is a broken man with a broken mind, essentially sexless, focused purely on his job. he gave up his life and happiness in pursuit of justice. instead of accepting the rejection, diana tells him he has more than earned some happiness in his life.
from then on she sticks close to him privately and publicly, slowly worming her way in. he resists, because he doesnt want her to get hurt or waste her time on him. eventually she rekindles his humanity and he begins to find himself enjoying her company.
fast forward to regaining his sex drive, diana has only dreamed of the moment. bruce is a large man. his imposing figure triggers ancient primal instincts in her dna. submissive ones. in the heat of the moment she finds herself being dominated by a man whos taking out 30 years of sexual frustration on one woman.
after that theyre a fairly normal couple, but bruce still struggles with retaining his new personality and outlook sometimes
