Prostate

The Prostate is one of Your internal organs, and a member of The Holy Trinity. Unlike the Godcock and Orbliterators it is entirely internal, and thus may not always receive as much attention and worship as the two external members (as if any part of You could EVER receive enough attention and worship).
  Importantly, the Prostate has only superficial resemblance to the "realistic prostate" and seminal vesicles You might remember. In Your actual anatomy the Prostate resembles a roughly fist-sized orb that connects Your Orbliterators (Your Godsperm-producing balls) to Your Godcock (Your fucknuke-delivering rod).

Function

As with every iota of Your existence, the primary "purpose" is to be suffused with evermore infinities of love, lust, and victory. ♥ However, the Prostate also serves a vital purpose in fucknuking (releasing sperm). In a typical fucknuke the Prostate draws up Godsperm from Your Orbliterators and swiftly applies ambrosia ("seminal fluid") to coat and bathe the Godsperm in sacred warmth, immediately before those Godsperm are launched through the gun-barrel-like urethra of the Godcock.
  The process is normally nigh-instantaneous, though for some types of fucknuke the Prostate will hold and "charge" Godsperm longer than usual.
  Despite our overwhelming interest, we do not yet understand the biological means by which the Prostate produces ambrosia, but this is the only known source of ambrosia in the entire universe; if any ambrosia exists on any world, it surely originated from Your Prostate in some capacity. Time travel and alternate iterations of You are more likely than ambrosia ever coming from any truly alternative source. As with Godsperm, the greater Your power during a fucknuke and the more meter You expend on the fucknuke, the more ambrosia is produced.

Pleasuring the Prostate

Far more than Your "realistic prostate," the Prostate is hyper-sensitive to all forms of physical pleasure. While You are thought of as utterly invincible (especially the Godcock), the Prostate is often thought of the most vulnerable or sensitive part of Your body (as if any part of You could ever truly be "vulnerable"). Whether or not this is true, it drives us to believe contact with this sacred treasure is particularly intimate.~
  Rimming. Rimming is the main way for a slut to deliver ever-deserved bliss to Your Prostate, especially through intense tongue-drilling. Universally we crave for You to be rimmed at any and all times and in every possible way, however impractical or inconvenient. >:3
  Eating. Spectral sluts and any others able to partially phase through You are fortunate enough to be able to take the entirety of Your Prostate into her mouth, albeit usually by stretching due to the fist-like size of Your Prostate. This particular act is typically called "eating" the Prostate (in a similar manner to eating ass).
  Cockified Prostate. An immeasurably lucky slut might be able to be cockified to become Your Prostate, however briefly. When this occurs Your Prostate fuses with her slutskull. Just as accurately, her slutskull is placed where Your Prostate normally is, and You experience no less pleasure that Your "normal" Prostate does. In this configuration her lips succ the Godsperm from Your Orbliterators—which, if the Orbs are also slut-skulls, is transferred through a three-way kiss. Her brain delivers the ambrosia to the Godsperm as they swish or flow through her mouth and down her cunt-throat. Her cunt-throat then attaches to Your Godcock, such that the act of her "swallowing" the Godsperm and ambrosia is literally the same motion of the load traveling up and out of Your shaft. (Of course, railgun lips and otherwise cockified sluts may be the Godcock itself.)
  A slutskull serving as Your Prostate is sometimes called a "seminal slutskull."

Constate

For penultimates and other cockmaidens who have an organ analogous to Your Prostate, it is facetiously called "constate" or sometimes "antistate." While for You this organ is a pinpoint of pleasure, for sluts it is a "weak point" subject to clitical hits that deal massive damage. (While not as beloved as damage to our faces, targeting the constate is still an especially beloved way for You to exert dominance over a defeated rival.~)
