It doesn't really matter if there is actual explicit content of the girls with other men or not. You can already sense implications of that sort. It's already abundantly clear, in both games, that bad choices bring bad consequences for the girls.
Competition between men is a very present element in Caribdis' work. Remember James, Oliver, and the specific *way* that you are tormented in one of the bad endings, as well as some of the things Astaroth says to you. Not to mention the fact that one of your main love intetests is married to and mistreated by the ultimate antagonist! I'd say it's more present than I might feel from other works. Even Tom, while not really a *romantic* threat, is very much a physical/sexual threat.
We already have plenty of bad things happen to the girls if you choose poorly, including advances of other men portrayed *as* bad things. Penny strips for a lecherous abuser and is so distraught she renounces her whole dream. Annie has her heart shattered only for you to twist the knife by sending her a shirtless pic. Dalia, a self-reliant woman who already doesn't trust easily, is consummately betrayed, robbed of a special and precious place by people who have been horrible to her. Penny is betrayed and taunted by a social enemy. Then there's the advances of other men, portrayed as bad things: Dalia considers giving Jerry a chance. Nancy allows advances from the yoga instructor.
These outcomes are already bad enough, the message clear enough. It's inconsequential whether rape is used to dial it up even more, that's just sharper dressing on the same flavor.
