Before his untimely demise, thanks to an accidental overdose, Derek's father had actually taken the time to teach him about the birds and the bees. The whole thing had been incredibly awkward.
Made even worse by the fact that while Derek had been blushing red all the way from the tips of his ears to his pinky toes. His father had been stone-faced talking about sex and the human anatomy without his expression ever changing. Listing off everything as though he were talking about the weather or some other equally bland topic. And his father had not just talked, he had brought visual aids too.
He had even been considerate enough to come with a cucumber and a condom so that he could demonstrate exactly what he was talking about to Derek.
Back then, twelve year old Derek had been of the mind that he was scarred for life. But as he had grown, he had come to realize how valuable those lessons were.
