Im leaving for Peru in about a week for a week and need some advice on how to go about starting a fling with someone.

For some context, I don’t have any experience hooking up, haven’t had sex in 2+ years, and only ever been with one girl a handful of times. Long story. Anyway, I am going on a trip with a group of random people from all over the US to Peru, 3:1 ratio of girls to guys. I haven’t had a better opportunity to try and hook up with someone, but I’ve never established any kind of relationship like that before. I don’t wanna miss out on hints or an opportunity but I also don’t wanna seem like a creep and be shunned for the whole trip because I tried to get with someone. I really need some advice because this is uncharted territory for me. Thanks!
