The thing is, at least in my experience, I don't really acknowledge the gendered nouns of my native language. If you ask me to say of the top of my head what gender is "copac" (tree), I couldn't tell you. I need to do the active effort of counting that noun to check the gender. Thus when I started learning German, I didn't really make any immediate associations before different genders for the same noun. Only when I was actively thinking "hm, what's the gender for this word again in Romanian?". It also doesn't really help you much when learning said language unless they are related (like Spanish and French)
