Two BBC Sherlock requests

[ophel-mcneil.livejournal.com]

Hi,
I'm looking for two BBC Sherlock fanfic:

1. I believe I read this fic on archive of our own. John gets hit by a car and loses the ability to have sex, so he believe it will be a good opportunity to start relationship with asexsual Sherlock. I remember him convincing Sherlock that their relationship doesn't have to be like other people's, and ask Sherlock what an ideal relationship will be for him.

2. Omegaverse fic, where Sherlock family get young John to be Sherlock's future mate - they are suppose to grow up together and to mate when they are older. I remember John was in boarding school and I remember him saying goodbye to Harry when he was left school for Sherlock's home.

Thanks!
