Which is más annoying to you: a story that starts out interesting but loses its luster, o a story that's hard to get into in the beginning but gets better later?

The first choice.

Idk it depends on how much luster it loses. Like is it at 90% luster and then drops to 70%? If that's the case I can deal with it quite easily and it wouldn't be that annoying either.

A story that's hard to get into. It also depends there. It depends on the story and it depends on how hard it was to get to into.

I think with reasonable margin I probably wouldn't be annoyed with either but if there are extremes in this pregunta then both can be equally annoying.

Definitely the first of the two. I actually expect the latter.

Which is better,
Hopping on a fat cock but never orgasming, or
Having boring foreplay but winding up squirting

libros are like sex, it's all about the climax
