I'm quite late to the party here, but I'm guessing you mean the banner image displayed on top?
The reason that image is used is because it is a rendition of "The creation of Adam" by Michelangelo. The women here are being portrayed as the MC's angels and themes of godhood and granted powers play a big role in the story. If there is a deeper meaning as to why the MC is placed in the position of god while the actual 'god' in the story (the man on the bottom left) takes the place of Adam I do not know.
But no, I haven't seen anything in the game that would suggest the MC is gay or 'ignoring' the women.
