Need help figuring out what drink I like

Obviously you can’t know for sure, but you may have some guidance. I turned 21 back in the first week of May and have never really been interested in drinking, but going out with friends and then when they offer me a drink, I say I don’t drink, I get funny looks cause I just turned 21. Tried a few things and haven’t enjoyed them, I don’t like beer, I tried jack and Pepsi (bar didn’t have coke) didn’t like any of them. I mostly drink water, coke, orange juice, or milk. Anyone got any ideas?
