It's a difficult balancing act - the player has to identify with the MC but often the dev/writer wants the MC to be a specific character doing whatever is needed by the story. In this instance I had no problem being told that I'm madly in love with Lydia as that's a type that appeals to me, but I can absolutely see how it rubs other players the wrong way. I would have been livid if I were forced to deal with Lyssa as LI (and am still pissed about that unskippable BJ I absolutely wanted no part of).
The more I can project myself in the fairly generic MC, the more I want freedom to decide his/my actions. In Leap of Faith I kept being forced to do things I didn't want to in order to progress the story (going on the date with Kira, going to Robin's apartment, accepting Lexi's offer and inviting the other characters...). Hell, I didn't even want to choose a girl there, and being forced to do so without realising it at the time of the choice really rubbed me the wrong way.
Now I've just started Desert Stalker and that guy is SO different from me and living in a totally different world from ours that I can go along with dev-mandated choices more easily. Or play in a way very far removed from my normal style.
To be fair though, if you choose not to be interested in Lyssa's extras, you won't find out, so it's just a BJ by a girl, and you have dealt with worse. After all, the Fetish Locator app (in game) will entice you to do a lot of stuff and you cannot be guaranteed that everybody will be to your liking.
That is also what I want to add to your otherwise correct observations: the premise of this game - playing the FL app - in essence means, despite all choices, that we will see more weird action, maybe some we are uncomfortable with, than in the standard "Young man comes home to his landlady after 8 years" fare. So I have accepted stuff in this game for the reasons you lay out that I probably would count as a minus in most others - it fits the story.
This does not extend to Lydia though - I mean, I have accepted her as a forced LI even though I considered the smittenness (is that a word?) completely overdone, but the story premise did not necessarily call for any LI (as opposed to fuckbuddy) at all.
) and we have to watch MC try to get her..
