By him using fingers, and tongue. Without ability to climax, he could easily dominate the sex encounter, as pleasure would not cloud his mind. He could easily control his partner.

Huh.
Would definitely suck for him, but I can see how that could be useful.

A male sub in a cock cage is a common scene. It could be similar, without the edging.

Is there edging involved in a cock cage scene?

Oral sex is a thing. So is any penetration where they are on the receiving end. So the logistics of an eunuch in a sex scene are not the issue. Mainly the story reasons are a bigger question. Why is the eunuch in the story? What is in it for them?

Alternatively, he could also use a strap-on.

Oh! That's not hard (no pun intended!). Eunuchs are sterile, but not necessarily impotent. Or, even if impotent, can pleasure their partners in other ways. It becomes less about their need for release, and more about focussing on what their partner responds to - perhaps even guiding or coaching those responses - for example, a eunuch guard preparing a concubine for their role.
