I'm really shocked at some of the names being used to describe this girl who none of us know. Why aren't you calling the boy names too? Is he also a tart? Are we back in a decade where young girls who are sexually curious or misguided to believe sex will make them popular or get them attention are perceived and labelled as 'tarts' and 'madams'. Christ I really hope you don't have teenagers or work with them!
For a start, I didn't say she was a tart. I said what girls who behaved like she seems to be doing were called back in the day.
WE don't know her. But we know what the OP has said. Based on that, she seems to be driving the 'relationship' and her son is asking his friends how to perform sexual acts- because he is only 13 and clearly doesn't have a clue. He's what- in Year 8?
She does seem precocious, yes. She is hounding a 13 yr old and saying very explicitly what she wants him to do, sexually.
If you don't understand that sexual activity is often a 'point scoring' even in schools/ amongst young people and some with low self esteem see sex as a way of increasing their appeal/ popularity, you need to do some reading about development in teenagers.
And FWIW I am horrified that your sister put her child on the Pill at 14 and condoned under age sex. For a start, it's illegal, and the law is there partly or protect the emotions of young people not just prevent pregnancy. Being on the Pill is no guarantee of an unwanted baby- young girls are known to be lax with pill-taking and it often fails.
Any parent who condones sex at 14 between two children needs help.
And yes I did have teens and they are now wonderful adults, in their late 20s, with well-adjusted relationships.
What about you?
