DAE know more terms in one language than the other?

Native speaker of English & Spanish. Born in the US, technically, but we moved because of some job my dad had, I think.

He decided to stay in South America, and when I learned about certain things via friends, school, and the Internet, they happened to be in Spanish.

My parents, who I spoke English and Spanish with, didn’t really teach me certain adult stuff, so I learned through literature and school assignments (but also TV).

(So sexual topics and topics related to drugs I learned in Spanish)
