Not the futa Marina I was expecting.

Anyway, you missed the entire point of the discussion.
To answer your question, A shemale can give birth through his immense cock and hold his babies in his balls, not necessarily through wombs that you hate so much. With a blatant display of the emphasis of only gigantic cocks and balls with no vagina hole whatsoever, this is clearly a shemale, NOT FUTANARI.

This what makes it different between a this site's definition (and probably real definition)of futanari and "your definition" and you lots/ilks definition of futanari. Until this is rectified, I will keep saying this.

FUTA = two sexual organs (both male and female sexual organs are present, i.e., dicks/balls and vagina) with breasts.
SHEMALE = he only has male sexual organs with breasts (often gigantic)

This is very important because some people strongly dislike the presence of only dicks and ball and no vagina or whatsoever. This is one extreme example.

This is the definition:
Dickgirls
Futanari - Penis with a vagina still present (may not be visible) on a female. If the vagina is not shown, it is assumed if the penis is shown but no testicles are present.
Shemale - Penis and testicles present with no vagina on a female. Assumed when testicles are shown whilst a vagina is not.

In this gallery, the testicles and balls are clearly shown even highlighted. And no vagina at all
