It's really important to keep being relaxed yourself with your own nudity. Research shows ( I read it recently in an article but can't find it at the mo) that girls delay starting sexual activity when there families are comfortable with nudity.

It's also vital to use correct terminology with children. Yes boys/ men have testicles, scrotums and a penis and girls/ women have a vulva and vagina. So many people call the female genitals a vagina but its more accurate for a child to use the word vulva. Using correct terminology helps to reduce or eliminate any shame with our private parts. It's also is a clear indicator if( and I pray this never happens) your child has been interfered with. A person with bad intentions is more likely to use 'pet' names for body parts so If a child starts saying their 'hoohoo' is itchy, you have a clue that something might be up.
