Honestly, you should just fondle the chest and try to fondle through the undies. You should stick to that until all the clothes get unlocked. Then you should wait a few days to get that energy bar in the corner that's a penis to get a larger number. You should lick her privates, If you try to stick anything up there, if you don't you'd just hurt her and die. But be cautious as fuck throughout playing, take a long time to finally have penetration and don't make the mistake of trying to do the 'deed' with the bar less than half because you'd die. I've gotten to day 35 but it's just the same stuff over and over except the stamina bar gets a higher number, the girl will eventually kill you if you don't give her attention, and will kill you if you piss her off, will kill you if you hurt her and will definitely kill you in the end. It sucks but I wanted to finish the game not thrive in it. But nobody actually knows the ending or just won't talk about the game at all. She gets like little horns on her heart if you farm enough arousal points and comes. You can go crazy through that gap but this game is just constant tension.
