This is interesting to me. Before we ever got to the beach scene, Christine:
1) Sent a friend into the shower to try to seduce Adrian.
2) Made him break the law by planting a hidden webcam.
3) Made him watch her have sex with another woman.
4) Made him have sex in public where other people could see them.
5) Made him have a threesome with her and another woman.
Most of the people who didn't like Christine were turned off by the initial shower test. I'm surprised you made it to the end.
That said, the whole point of Coming to Grips with Christine was to give people who didn't like Christine an option to have Adrian find a relationship where he would be an equal partner. I didn't do telemetry or anything like that, but the impression I've gotten from comments is that people are pretty 50/50 on which they chose.
As for allowing you to skip a sex scene, a decade ago when I wrote GtkC, the concept of playing a sex game to not see the sex wasn't something any of us would have ever even thought of. Up to this point, all of the games in the genre were, "Meet a girl, and if you make the right choices, you win by getting a sex scene." In those days, I don't know why you would have played the games if you didn't want the sex scenes.
