I’m 22 and have never drank, any tips?

As the title says, I’m 22 and haven’t ever had a drop of alcohol. Not for any specific reason, I’ve just never seeked it out. I’m going to a small party on New Years and decided since there’s gonna be drinks I might as well have something finally. Idk exactly what will be there, but there’ll be a lot, anything from cheap canned beer to some more expensive stuff as a few of my friends drink a lot. Any tips for what I should try first/how much?
