Translation of penoso

My parents were Italian, but the first language I learned was Spanish, since we lived in southern Spain. Very close to Gibraltar. When I was older, like twelve I moved with them back to Lucca in Italy.
My mother tongue is Spanish. For one year I lived in Spain. I'm from Huston, Texas, USA, originally. I want to study Spanish literature next year. I have already been to my professor to discuss it.
