Alcohol doesn’t affect me?

When I drink beer ( corona, IPA etc.) I don’t get tipsy or at least some type of buzz. Only after 4 beers maybe 5 I feel something. Drinking drinks with hard liquor (vodka,rum) it takes a few (3-4) for me to get tipsy. I drink every 3-8 weeks and weigh 115 lb. I’m curious why? It’s something I wondering why is it
