Asexual!Sherlock

[shadowangele89.livejournal.com]

Hey,

I'm looking for a series. I know I read it on AO³ but can't find it now.
BBC!Sherlock is asexual but he and John are in a relationship, they don't have really sex but do otherthings instead like John washes Sherlock or massages his feet. John is content with this and loves it.
I think but I could be mixing fics they get married at the end and the series was finished?

I hope you reconise this series :)

Edit: I remembered some more. Sherlock experiments on John about what he likes, first Johns back, than his front and than on Sherlock. And they try that John gives him a BJ but it's to much sensory input for Sherlock and they have to stop. Sherlock was quiet upset about it.
And there was a Silvesterparty at the MET in the gym, but this could be a other fic I'm not sure.
