I live in a traditional European country, which is getting 'modernized'. We are not as sexualised as the US, but we are slowly getting there. I see the signs.

I have female cousins in my family, who have just entered adulthood or are about to. They are around 20 or less. I have decided, that they need to be taught about the reality they are about to face, before it's too late. Their parents are certainly not fit to do this. I have decided, that it's my moral duty and I care about their well-being. They are quite reasonable and listen to me. I need a list of key bullet points to go through with them.

Please TRP, help me do this right.

Edit 1: at 6 hours: Up to this point your replies have been defeatist. Telling me that I will fail is bad advice.
