Can’t get drunk!

First off I’m 18 years old and don’t drink often only for social reasons, but I can’t never get drunk not even tipsy I always chalked it up too high tolerance but recently I had a family gathering and everyone had lots and lots too drink I had 5 shots 3 beers 2 glasses of wine and a margarita and as I looked around everyone was stumbling there words tripping typical drunk stuff and I don’t even feel a single effect perfect and clear thinking no impaired motor functions and then it got my thinking every party I’ve ever been too I’m always the one bored cause I can’t get drunk, is this some kind of weird medical thing? I’m a ginger if that means anything, any feedback would be nice!
