Well to be very honest irrespective of the gender every child must be taught:
Firstly, to respect themselves and their body. It is only then that they will learn to respect others.
Secondly, to be honest. No matter what. Because one lie leads to a 1000 more and situation goes out of hand.
Thirdly, it’s okay to make mistakes as long as you are strong enough to stand for it and never repeat them again. And understand mistakes are an essential part of learning.
Once you are honest, loyalty comes hand in hand. It could be with friends, family or later in life when you meet someone special.
And lastly be bold and confident enough to stand against the wrong and always support the right.
