I sometimes call women as 'women' or 'girls' or 'females' all interchangably. Am I wrong in that?

Like.. while talking, I simply use any of the three, and to be fair, I treat/use all three words equally, without giving any thought to that. I can say 'girl' in a sentence and in the next sentence, 'woman'.

Can it be hurtful to some girls, or is it just something someone might not prefer. Or are most women okay with it.

I do the same with 'men', 'boys', 'males'.

I don't call them 'aurat' or 'mard' in hindi though. I can't point out, but both these words make my own tongue a bit uncomfortable though.
