Sherlock Holmes Fic Finding Community

Hope someone can help me find this. Read it years ago. It was bbc verse. Sherlock had deduced that john was attracted to him but was waiting for john to make the first move. John doesnt so sherlock eventually kisses him which goes well except when the kiss is over john denies being gay/attracted. I cant remeber how but Sherlock convinces john to try a relationship and agrees to go very slow. Sherlock eventually deduces that john had a previous homosexual relationzhip but it was abusive. John wont tell him who. Sherlock spends month carefully and lovingly helping john learn a real relationship and how homosexual sex should actually feel. Last seen has them in tbe park sitting next to each other holding hands after john had run away after cinally realizing just how abused he had been by the previous lover.

Any ideas?
