Ever start trying to get off to one thing, and then you think of something else to get off on so you search for the new thing, and then a few seconds later you think of something else? It is like ADHD, but for porn. Anyone else have the same problem?

Nah, I just use fav:furrin_gok order:random and bounce around images there. Why waste time and effort thinking up something when you already got a bunch of stuff in your favorites to do that for you?

If you're referring to getting sidetracked, yes. Although in my case, it's rarely porn.

Make a list of tags, slap them on your profile. Same with artist names and complex searches.

The nice thing about having oddly specific niche fetishes is that there's a few specific things that do it reliably and few alternatives to get distracted by. Finding art/videos of those few specific things however is another story.

May get a nice idea or two during a session but not so often and distracting like you mentioned.

I usually do a variant of this where, in the middle of the day "Hey, I wonder if there's any rule 34 of [really obscure character or creature]!"
Then by the time I'm at a computer later I forget what they all were.

interesting inputs so far

All the time, I'm looking at one kind of thing and either randomly think of another or click on a tag which leads to more and more like a chain of tag clicks with filtered results like gender, view point or position. It's the best way to use this site IMO
