Well, according to devs pov - the game is meant to be hard from the start and challenging, so any progress you make is more rewarding.
It's not supposed to be another shallow sex sim, rather a full fledged game with various engaging minigames and other mechanics, so you learn from your mistakes how to overcome certain obstacles.
Imo, what you described, is pure skill issue and shattered expectations where you wanted a simple sex game and got some kind of dark souls wannabe adult game.
I'm sure you'll get it eventually.
Cheers
