I've been to hundreds and do have the tinnitus but it doesn't much bother me at all. I rarely go anymore because of unrelated reasons, but it was all worth it.
I worry because I hear it gets progressively worse even after you've stopped exposing yourself to extreme volumes. I raw-dogged two or three shows that were way too loud to be at without protection and that was enough for one ear to have significantly worse hearing than the other, that's what finally made me start using those musician earplugs. But apparently I can expect the ringing and loss of hearing to continue getting worse anyways...
