It was just 5k miles ago I put Mobil tranny fluid in there. Does it go bad that quick?
Are you absolutely sure you have the right fluid in your transmission? Everyone here seems to recommend either Honda OEM Tranny fluid or GM synchromesh Friction Modified.

I wasn't aware that Mobil made a tranny fluid for our car. If the Mobil fluid that you use was Mobil 1 75w90, that goes in the rear differential and not the tranny.

The diff fluid shouldn't affect the way your tranny shifter feels.

For the tranny fluid, you have to get under the car to check it. There's a fill bolt and a drain bolt. Instead of checking it, I suggest you change the fluid if you haven't done so already. Here's a how to written by xviper:

I suggest using Honda OEM Manual Transmission Fluid. Buy 2 quarts of this. You'll end up using about 1 1/2 quarts.

Skipping gears on this car is a no-no.

Here's a thread that explains why. Woodwork is an engineer over at American Honda that specializes in the S2000.

Since this problem as gotten a bit worse, does this mean I have a possible leak somewhere, or does this happen after the tranny fluid gets old?

If the tranny fluid replacement fixes it, it's because the tranny fluid needed to be replaced, which is very common.

If you did nothing wrong and this described problem happened over time like you say, odds are that it's just old fluid. I just did my tranny fluid, which was a breeze. Used Honda MTF for $5 a quart.

it might not be the same problem.. but
When I had a prelude (my first stick), I never rev-matched for one and half years.

In the beginning, it was pretty hard to put in gear sometimes. and then it got worse slowly.
When me and my friend opened up the tranny, there was bad wear on clutch.
Not on the clutch disk, but on the thing that holds the spring. (4 springs around the center to relieve engagement shock).

One side had so much wear, the spring almost came out. The new clutch (ACT) solved the problem and since then I always rev-match.
