vodka for a first-timer

I wanna drink vodka with someone to feel more confident and maybe slightly tipsy but absolutely not drunk. We’re gonna be in somewhat of a risky place (just for the adventure lol) but it’s our first time.

Any advices you guys have? What should I do? Would 2-3 sips be enough? We’re 20 years old if that helps

Also I thought about beer but I feel like it wouldn’t do anything since 5-10% alcohol would be a bit too low. but again idk much about this stuff.
