Grrrrrrrrrr!
Masculine/feminine words aren't actually related to male/female except in grammer. Most masculine words end with 'o'. Most feminine words end with 'a'. If a word ends with 'este' it can be either. If a word doesn't end with 'o', 'a', or 'este', most of the time you can assume it's masculine.
Each word has gender. This gender is only grammatical, and does nothing but dictate which adjectives/pronouns to use for that word. Some are masculine, some are feminine.
Hmmm, an interesting question, why not ask the same of feminine? En todo caso bienvenida al foro.
