>Is there a psychological explanation for this
You have little going on for you in terms of being attractive to women besides "I'm a guy, girls like guys, right?" so the idea of a girl not being interested in that single redeeming feature is threatening. You then fantasize about a world in which simply having a dick is a superpower such that not just girls who like dicks, but even girls who aren't interested in you at all will just desperately swoon at the chance to touch your penis. You hate normal NTR because being a guy doesn't afford this power fantasy. The guy being NTR'd has being a guy going for him and still lost the straight girl, and you lack the confidence to associate/self-insert as the guy she is cheating with.
tl;dr
Yuri NTR is the fantasy that just having a dick means you could automatically win girls who "don't like you".
NTR NTR confronts you with the fact that there are just better guys out there that have more appeal to women than you ever will.
