It all depends on my mood...
9 times out of 10 I look for a well told story and plot to go along with my erotic content... A healthy and balanced mix is always good if done right... And I'm always a sucker for a romance story, or multiple romance stories, or romance alongside some lust, etc...
It does not need to get to the sexual stuff right out the gate, as I see many VN/Game starters do this, and it usually is just to entice donations rather then initiate a good VN/Game... It's a money ploy in most cases, not usually a good beginning to a story based VN/Game... It is rare that it feels like a natural part of the story most of the time, when used...
I don't mind if it's a grinder, as long as I don't have to spend hours to see anything worth while... I don't mind an Adventure based grinder as long as it gives me hints via well told story/dialogue and what not, rather then me having to look it up online, use a walk-through, or have to spend hours trying to figure it out... I don't mind a stat grinder, as long as I don't have to spend hours trying to figure out if a given stat even matters for gated content, or spend hours to find out I missed half the content because no hints were given that I was working on the wrong stats at the wrong moments and there is no going back, or having to spend hours seeing the same thing over and over and over again raising a few stats just to see a few brief moments of new content and then have to do that again for the next tiny fraction of content...
I will usually prefer well told choose your own adventure Visual Novel style game play... I don't mind a little navigation here and there either, as long as it's not hard to figure out what to do or where to go next to get to the next Visual Novel style content...
I do not want choices to be damned if you do and damned if you don't, as I do not like player/reader punishment... Even worse are game overs part way into playing/reading due to a choice where there was no hint given that the path would lead to a game over... And I hate it when you are placed in control of the destiny of a protagonist, that is doomed to be the victim no matter the path you choose...
