Pardon the inherent ickiness of asking how an android and a human...become intimate, but this has genuinely puzzled me since I watched the Next Generation episode "The Naked Now." The summary for the episode on Memory Alpha states:
She asks how "functional" Data is; he replies he is fully functional and is programmed in many "techniques," a wide variety of pleasuring. She leads him to her bedroom, where Data gives a programmed smile. The door closes.
I'm not asking for specific details because, honestly, ick-factor, but:
What does "fully functional" really mean?
Why was Data built to perform a "wide variety of pleasuring"?
Also, I will not be offended by close votes. This question is insane.
