The context of this sentence is this: I studied French and Italian first...then my mom married a cuban guy and I got very curious about Spanish too and started studying it.
PLEASE the most important thing is for this sentence to sound like something a native would say, not a foreigner learning Spanish. Please feel free to correct it to sound more natural, thank you SOOOO much! :D
Y porque mi padrastro era cubano, tenía mucha curiosidad por el español.
