Sherlock frowned, leaning away a little. Sadness and embarrassment clouded his face.

"I... I didn't know.. I was just a human, a mortal." He looked down, not wanting to meet John's face. "I... have been with people, male and female."

Sherlock started to lean back. "I understand if you are upset, if you want me to stop." He was Hades, but he was still a bit of Sherlock, not as evil or as cruel as he had been as a god alone. This.. of all things. helped him really understand human emotions.
