Damian is in an open relationship with Natalie, so you will definitely fuck him at some point, probably (hopefully) both him and Natalie at the same time.
I don't think that's how most people approach games with a female MC. Think of it more like porn, you don't watch videos only starring the same guy, do you? It's fine if you do, that just seems weird to me. To me it's about choosing a playthrough, and relating to the guy she is choosing in that run. If you do the full bad girl path, it's like watching a female spotlight porn, like I enjoy "Tori Black is Pretty Filthy" because I like seeing Tori Black take dick in a variety of ways, not because I want to get fucked like Tori Black by a variety of guys.
