Inability to get tipsy/drunk/feel any alcohol (as a non-drinker)

hi! this is my first reddit post, and i’m not sure if this is the right subreddit but i am in search for answers because i can’t find anything on my experience. i, 18 year old female, have recently drank for the first couple of times in my life and was unable to feel any effects of alcohol. as of right now i’ve only drank on 2 occasions, i thought hmm maybe i didn’t drink enough the first time, which was 4 months ago, (even though i had about 5 shots of gin, 8 shots of vodka, a shot of malibu and whatever else i could sip on trying to be a rebellious teen at a party) and felt nothing, not even tipsy, i didn’t think too much of it until i drank again for the second time. Nothing again on the second occasion after having 6 full glasses of some type of vodka cocktail at a family party (18 year olds get to drink at our family functions) i was unable to feel tipsy/ drunk/ anything at all especially compared to the fact that i had the most to drink compared to everyone around me in both instances. the first occasion partiers were throwing up and hungover and i never felt bad once, even though i had the most to drink. then at the family party after a glass or 2 of the cocktail the other ladies at the party were saying how strong it was and how they were already tipsy. So at this point i don’t even think this is a high alcohol tolerance thing because then i would at least feel something, anything, at least tipsy, but i haven’t felt anything. could this be an inability to break down alcohol, is that even a thing? i have seen where some people don’t feel anything but they will still have physical symptoms of drinking, stomache cramps or dehydration, but i didn’t feel anything like that either. if anyone has had a similar experience or knows possibly what could be going on please let me know!
