Why do i not get drunk

Guys i drink like 2-3 times a year and i never get drunk. I could drink about 15 shots and still be fine, the most i feel is just sleepiness but thats it. Im conscious, can still do calculus, identify the people around me, walk in a straight line, does anyone know what could possibly be up? 🥲🥲🥲🥲 I feel like im missing out when i see my friends getting wasted. Also the shots were tequila, vodka, soju 💔💔💔💔💔
