There's absolutely nothing wrong with your clutch.
There is, however, a way to test it, and it is not very good for you clutch if you do it all the time.
Take your car to a complete stop. Raise the handbrake, and shift into second gear. Try to move your car forwards as if your starting in 1st gear. If your car stalls...then that means your clutch is in great shape...and new! If your car starts creeping towards the front...then you are also ok. If your car, however, does not move...then engine does not stall if you have pulled away your foot from the clutch...then you are in trouble and in need of a new one!
Note that your clutch is never the same any time of the day. It de-clutches in different positions throughout the day, mainly depending on the temperature of that time. If you are racing...and you are pushing too much the car...then you would feel that you need more gas now than before when shifting. That's normal cause it is very hot.
A way to see that you are having a problematic clutch, like mine in my Alfa Romeo here in Greece, is that when you start your car with first normally as you always did at about 1,000rpms removing your foot gradually from the clutch...your engine starts to shake! You feel very large vibrations coming from the engine. That means that your clutch is grabing your flywheel then releasing then grabing again...and you need more gas to start driving.
Now...if you keep pushing the gas pedal...releasing the clutch and nothing happens...your clutch is all eaten out!
That's all I can offer for now for a small clutch lesson from all of Europeans here that use stick-shifts.
