Sherlock wanted to say those words.. He did.. he really did, but he couldn't find a way to make his lips formed the words..

Instead he leaned up and kissed John fully, arching up as his hands wandered down John's front, his broad long fingers finding John's pecs and his nipples, teasing and twisting at them, watching his lover move above him. Even on the bottom, he was still the one in control.

he found that he liked this position, quite a lot.
