Preferably harem, but it's okay if only one girl fighting for the MC's attention. But just to be clear, I don't mean the yandere type where she manipulates him, but rather in a submissive way, where she wants to be noticed and become his.
Also, if the MC is a pushover and naive about sex, forget it.
Pornhwas that fits the description:
Ulocking her heart - Mostly the girl with white hair, but they are all submissive to some extent and low key compete with each other. (image 2, 3 and 4)
Whats for today dinner? - Theres one girl(I forgot her name) that was obssessed with him and pratically begged for him to take her. (Image 1)
Bad guy - My favorite. All the girls seek his approval and are always competing with each other. They are all submissive and devoted to him. (Image 5, 6 and 7)
