Russian (read the rest of the post imagining strong Russian accent and vodka smelling breath).
I was like 4 years old, Soviet Union was living out it's last days. My parents found a private teacher for me to study English basics, and I can't thank them enough. I didn't study it long enough to get good at it, but many years later, when I became obsessed with old video RPG games, it came so easy to me.
We also had lots of pirated VHS cassettes with poorly translated American movies, so you could ignore what the interpretor says and just try to understand the original text. It was pretty absurd, but after the crash of Soviet Empire, they have even translated porn
In my teenage years I listened nothing but British and American rock music. Led Zeppelin, Deep Purple, Black Sabbath, Grand Funk Railroad, Creedence Clearwater Revival. So for me (and I think for the majority of rock music fans worldwide) English is the only real rock and metal language. Trying to understand lyrics, to sing along with it and to imitate it in some of my own first "songs" was an important part of my life.
Then, when Internet appeared in my life (somewhere around 1998-1999 I think), everything useful one could find in music, sound engineering and games was mostly in English. It was complicated to read lots and lots of English text with Internet slang and stuff like that back then, but I can't imagine my life without it now. Sure thing, "Ru-net" is a huge now, and you can live without knowing English, but it's very limiting.
