Well, I'll butt in here, but, the way I see it everything that leads up to sex is the important part, like how many ways can you fuck? We've all seen porn, I believe that a big portion of us had sex, there is a limit to how many ways you can spice up the bedroom fun. Oh now you are fucking her in doggy and before that she was riding you, add to that some toys and the a few more positions and that's about it, everyone with a few years on the internet would've seen it all even if said person is a virgin. Of course when you are having sex with a person you genuinely like or even better love it becomes different, but I truly hope none of us here are actually falling in love with fictional characters. Therefore for me at least I see it as everything before the actual penetration and perhaps after the act as the most important, i.e. the build up and the climax. Which is why I like this game a lot, it builds up really well. But like you said it is personal in the end of the day, so to each their own.
