I don't want to repeat anything that's already been said here, but I do want to say that it's not something you should particularly worry about. Even though there are some speaking patterns that differ between male and female speech, it's not to the extent that you'll have trouble understanding one but not the other.
Just focus on your own speech pattern--I'm guessing you're male because you don't know the female patterns--and you'll be just fine. Besides, for every example of female speech you're given, there will be a counterexample where a man has used the same speech pattern. Outside of, say, a woman using 'ore' or a guy ending every sentence with 'wa', there are very few instances where incorrect usage would be considered overly innapropriate.
