Beginner alcohols?

Hello! I want to try actually drinking for the first time (not just taking a sip from someone else’s drink), but I’m not sure where to start. I’m 21, almost 22.

For flavors I enjoy, I really like sour and tart flavors, and sweet & fruity flavors. I do NOT like bitter tastes.

I’ve had a few sips bud light, which I hated. I’ve tried a pomegranate martini, it tasted like medicine to me, and then some sort of vodka and cranberry thing which was good.

What would you recommend for a beginner?

Also, I’d be drinking alone, as I don’t have anyone who I feel safe enough with where I live to drink with me, so anything I should know or possibly expect? Eat food, drink water, lower alcohol content…but what else?
