I’ve had 10 drinks but I dont feel all that drunk

I drink a lot. 2-4 times a week, 6-9 drinks during. I’m 210lbs and have a natural Irish tolerance. I’ve been doing this for over 8 years since I was 17. Even so, my tolerance shouldn’t be this damn high should it? I’m sitting here at 11 drinks and I feel only normally drunk. I’m not vomiting or having any sort of spins or negative symptoms, I just feel alright and somewhat drunk. Is this normal?
