I'm 21 and right now i would say i have a healthy sex-drive for someone my age, but its no where near where it was when a was 15, 16, 17 age-range. I'm beginning to worry that my decline in sex drive is an indication of declining test levels.

No, actually they are not, but it is probably a good gauge.
Other hormones can effect it (estrogen, progestin), and even simply how often you pop wood. Someone with erectile disfunction could well have a normal T level, but no will to have sex without something to remind them that they want it.
