I'd probably be traumatised for life if ever I found out that it does belong to her! 
Most Mums had, and have sex now and then, and hopefully they love/loved having sex. 
No no no! No they don't! Parents are just them old people that nag you. I was brought into this world in a blanket held by a stalk.
I refuse to believe otherwise. 
It's OK. Some parents think the same about their kids, that they never, never ever will have sex.
Always nice to share a delusion.

A stalk? I that the same as a stork?
