Akira Toriyama, sometimes. Watched a video by MasakoX (voice of Goku in DB Abridged) and, according to Tori-bot, Goku's never kissed his wife or been emotionally intimate with her in the slightest. Yet, she is still somehow married to him.
...And this, my friends, is Exhibit A in "Tori-bot Doesn't Have A God Damned Clue What He's On About." Just assume, for a second, that other than her power, Chi-Chi is an otherwise perfectly average human woman. Now, what's kind of critical in human relationships? If you said "emotional (if not physical) intimacy," then you win! Unless Chi-Chi is that one in some ten million or so, then being able to emotionally connect to her partner isn't a suggestion, it is a prerequisite for a stable, happy relationship, let alone a marriage. That's why Spock and Uhura would never work: Spock is almost totally emotionally unavailable. Eventually the litany of "that was a satisfactory performance" would drive Uhura insane and she'd dump his pointy-eared ass. Same with Chi-Chi: eventually, the lack of emotional support and mutual understanding would drive a wedge between her and Goku and she'd either A) divorce him, B) try and keep the marriage together "for the children" (which would NOT produce the otherwise normal, stable children we see in Gohan and Goten), or C) drive her to get a side man to fill the void Goku refuses to go near.
Now, if a lack of emotional availability is a "Saiyan trait," then that's all well and good, but then what the hell do you call Vegeta? The man quite obviously loves both his wife and his son (at least, by the end of Z) and rushed a fucking god because said god dared lay a hand on his wife. He did everything, even going so far as to humiliate himself, to protect her and his son. Again, assuming Vegeta is an otherwise average Saiyan, then none of this would be a thing.
Tori-bot, look, I get that you're not good with romance and whatnot, everybody has their weaknesses and its totally cool. BUT, for fuck's sake, you could've at least said that you don't want to really write that kind of stuff and that viewers are free to imagine it going on off-screen. THAT, at least, would've made sense. Its not like the whole emotional connection thing is some obscure psychological trivia, its a well-known fact of human romantic relationships. Ten seconds and Google can tell ya that. You could argue that "its a fantasy world" and "the normal rules don't apply" and, I dunno...maybe? It just pisses me off when writers willfully ignore fundamental parts of basic human psychology when writing human characters. Again, you don't need to be a psych major to know this shit.
