[In general, Sherlocks and Tonies have sex. With each other. It's not the best surprise to get, so when I thought of it I asked your Sherlock, and this world's not an exception. Your Sherlock and Other Tony haven't with each other, too busy so far, and your Sherlock says he'll clear it with you beforehand if an opportunity even crops up. So, note that when you have your monogamy conversation.]
