I can understand that but, if I was to offer some criticism about it, the two of them don't really talk about much else. It seems that every conversation they have includes Jacqueline's sexual advances or discussion of Michael's sexual interests. Perhaps the two of them could have a scene where it doesn't come up and they just hang out as friends? Sexual tension doesn't have to be discussed to exist.Jacqueline's sexually liberated attitude is a crucial part of the story, essential to Kate's development. Skipping the scenes would make the story really disjointed.
I don't think the MC is forced to have sex with Jacqueline or Alexis. That's up to the player.
Seeing that Jacqueline has a very open marriage and discussing it with the sexually conventional Kate is important to understanding what Kate may (or may not) do down the line.
I hope that the player can have Max avoid any and all of the LI. I need to play through it again and see if it is possible to play as a celibate monk.
