The Unsullied from Game of Thrones we know were castrated as infants. The purpose is to enhance their battle skills by eliminating all sexual drives as a result of the lack of testosterone production.

In the scene in S7 where Greyworm pleasures Missandei it would appear that he still is capable of having erotic feelings towards women. Can anyone explain?

    This question is based on the false assumption that castrated males completely lose their sense of sexuality - especially Unsullied which get to be as old as infants or five years old (before castration). Human males are exposed to testosterone in the womb, which is often enough to develop the vast majority of male traits that make males male - of course it impacts sexual development (like voice deepening and sexual drive), but studies have shown that even newborn eunuchs develop a sexuality (usually hetero) Commented Aug 9, 2017 at 20:15

You did see what Missandei looked like naked, right? That pretty much took care of my suspension of disbelief. Smart casting on the part of the show, in that regard ("she's gotta be beautiful/hot enough to arouse a eunuch...")

A less joking take is that Greyworm formed an emotional attachment to her, more than lust, and their actions was more an expression of that deep, emotional caring that he has for her, more than physical desire. Hence his explanation to her about how he fears (not being able to see her if he should die) for the first time.

Pre-pubescent children, for example, form crushes or strong feelings that are not based on lust, but their emotions and feelings, so attraction doesn't have to be primarily sexual.

The actions in bed were from his desire to please her and express his feelings for her in a way that forms a more intimate, complete bond between them. This is kind of like how in actual marriages where one partner becomes impotent or loses arousal or desire, they still have relations, because it's not just a physical act but one of shared emotional intimacy and vulnerability. Plus being able to please her in that way, since she's not devoid of those feelings, can be satisfying in its own right. That's also pretty ground-breaking and unheard of for the Unsullied, but it at least doesn't defy what we know about human biology and medical science.

    So is Greyworm just a sullied now or is he still unsullied due to no phallic penetration?

    @SCFi - "Semi-sullied?" "Sorta-sullied?" "mostly-Unsullied?" Here's my "plot surprise" prediction (besides Oberon having faking his death and coming back to lead the armies of Dorne) - Greyworm dies, an Unsullied eunuch who eventually found the joy of love. They need a new eunuch leader to lead them. Who better to replace Greyworm who found "joy".... Grey..... joy... eunuch...... Theon!! Commented Aug 9, 2017 at 16:40

I created an account here just to answer this.

I too had this thought and did lots of research. In short Yes, eunuchs can be sexually active similarly to a unaltered male.

Here's a whole article about that scene, including an interview with a medical expert:

"Romantic and sexual urges are complex neurobiological phenomena that have multiple components," Dr. Peter Stahl, the Director of Male Reproductive and Sexual Medicine at Columbia University told us. "Feelings of sexual intimacy in men come from more than just their testicles — personal connectedness, trust, affection, admiration, physical closeness, and cognitive conceptions of sex are all important."
