I gave you an analogy equal in quality to your comment.

Fair enough.

I'll ignore the sex analogy, and I'll instead try to add something to the discussion you were having with kleinbl00:

It seems to me that your reason for using spoilers is that you want to avoid bad works (henceforth I will just use movies as the example, but the same applies to books, TV shows, etc.). This isn't completely off the mark, but what I have an issue with is that it sounds like you're using it too much. It's true that you can avoid some bad movies by having them spoiled, but by doing that, you're also depriving yourself of the fresh experience of a genuinely good movie. Isn't this throwing the baby out with the bathwater?

Sometimes, the suspense being built up can only be fully enjoyed once. That's not to say that it can't be enjoyed again, if the movie is genuinely good, but the emotional involvement is often dulled a little on subsequent viewings. By having everything spoiled, you are missing out on this heightened tension which is rooted in not knowing what's going to happen next. I'd argue that while it may be less of an intellectual excercise than watching a movie several times so you can get more details, it's a valuable EMOTIONAL experience. Isn't emotion the main component of art? The technical and intellectual aspects can be pleasing in their own right, but in my opinion they should be there to heighten, and add weight to, the emotional impact.

Some movies can be quite dense, to the point where they only become fully enjoyable upon multiple viewings, but this is by no means the rule, and as you become a more experienced and sophisticated viewer, you can handle more and more complex works on the first go. The ones that you can't, you can just watch again if you think they're worth it, or read a critique/interpretation right after viewing them.

Allow me to indulge in some armchair psychology: I think you like to have things spoiled so you can have more control over your experience. You fear wasting time on a sub-par work, and so you spoil all works, good and bad, for yourself, and the result is that you miss out on the highs of experiencing a great movie without prior knowledge, while simultaneously avoiding wasting your time on a disappointment. That is your prerogative. At the risk of sounding patronising, I suggest that you let go of these fears, and revel in the highs and lows that come with the loss of control.

My intent isn't to put you down or anything, I'm just trying to express what I think are the advantages of watching things unspoiled.

PS: Watching a bad movie can actually be quite enjoyable in its own right, if you afterwards try to describe WHY it's bad. I often go off on rants to my friends about how shit a movie is, and why, and I find that to be tremendously enjoyable.
