New to this

I recently turned 21 and have been trying some things and was wondering what it usually takes people to get a buzz or to get drunk? I had just over 3/4 of a bottle of 15%abv bourbon whiskey over the course of about 4 hours on Sunday and didnt feel anything different, none of what everyone else describes when they get a buzz or get drunk. (Side note that was my first time drinking so I have 0 clue what is normal in terms of alcohol consumption, abv, proof, or amount or time.)
