Sex scenes viewers are dull (similar to games that are basically just that). They lack imapact, because they lack context and agency.
How you get to that scene and the contex to it (relationships, situation, etc.) add flavor.
Consider a scene of one girl eating another out. Nothing too wild? Now let's change context.
One is a school bully that is forcing the other to eat her (or is eating her).
OR they are strangers, being forced at gunpoint to lez out? Perhaps mother/daughter?
Then things that happened before can add extra weight, change the emotional states... add spice.
That siad, if if wasn't obvious by now, I'm big into yuri and futaxfemale, and this game is sadly lacking in both departments.
And while I'm not opposed to a female getting raped, I do hate it when a player character lacks agency and options. Cahracter A can do 15 things, character B can do 2. It just sucks.
