You mentioned a dislike of length and brought up Gwen's sex scene, which was 2nd to the longest one. So... I don't understand what's wrong—there must be more to it. If you don't mind elaborating further, it would help us a ton.
Well I didn't mind the length of that one cause of the build up and context that lead up to it. But with the others I found myself just wanting to get back to the story more or less don't got a real explanation as to why I disliked the others than it just didn't click with me as much and wanted get back to the story more or less. Been awhile so I could be wrong but maybe I felt there was a bit to much dialogue during it not 100% sure. I just kind of found my self wanting to move on after the first round and not to go for a 2nd round of sex most of the time.
It's more of a me issue im guessing. Cause Emma for example does have good build up and context but I really don't like Emma all that much. I liked how her character was more in the past but present ( for lack of a better word) Emma feels to robotic to me that I have a hard time liking her after all the changes she has gone through. So I don't feel anything for her in the present all that much so I can't get into her lewd scene and wanted to get back to more story asap.
But other than Sky and Emma I do like the other characters and I still have a hard time enjoying most of their lewd scenes past the 1/2 way point most of the time and wanted to just move on. So If I had to guess I'd say it's a combo of me wanting to just "move on for more story or just non sexual interactions" , "an me issue" and maybe I felt like there was a bit to much dialogue at times during them ( tho I could be wrong on this one).
I know that's not to helpful and sorry about that but it's the best I can do
