Am I being too jealous?

So me (lesbian, 27f) and my gf (bi 25f) have been together for over a year, coming from being best friends. Our relationship is wondeeful and we barely fight. We only had 2 discussions in our whole relationship and that is regarding our boundaries around other people. Meaning when is something flirting and when not.

Im belgian and more reserved mindset and she is spanish and much more open. She dances(like bachata or salsa) with random guys and girls just for fun because its normal in their culture but for me for example not.

We are unable to reach common ground on this, how would you solve this? And am I too controlling/jealous if I dont want to see her dance with random guys/girls or talk for like 1 hr straight to someone who is clearly interested in her?
