Thank you for playing! No such themes will ever be in the game. The only male who can have sexual interactions with the females is you. So no ntr, no cheating, no swinging, no hate/revenge sex etc.
The option where you say “let someone else take the pictures” + “review photos later” means that you will skip photography mini-games (those give you more content and additional scenes) but also increase the chance of you losing her interest because you did not take the pictures that she wanted if done incorrectly.
