There's a lot of lost in translation when we watch and discuss NTR titles. The problem is definition of the word r*** is changing and different between peopls and cultures. This is huge oversimplification but I'll do it anyway: I will cut the single word r***/NTR to three different levels:
1. misogynism: the woman does not want the sex and the fucking action is performed against her will, often (but not always) the only purpose of the action is to hurt her, not to satisfy the libido of the r**ist. This is a huge genre of JAV, a very common trope is the use of probes and vibrator on the woman especially in cavity other than vagina. Say, nose hook.
2. No-means-yes: the woman starts with verbal or actions to resists, for some reasons, but the r**ist purpose is to have sexual pleasure and possibily to give her sexual pleasure as well. So after some resistance, she accepts and often enjoy the actual fucking actions. The mildest form can be just a reflex reaction: the woman doesn't mind sex with this man at all, but community expectation dictates she must pretend a bit of resistance, at least until some clothings have been removed. Sometimes she started genuinely not accepting sex but the r**ist's sexual skillz is so amazing that physical orgasm overcome her mental resistance. One of my own fav is IPX-548. Minami also played in this series before, in IPX-358.
3. r***-play: the woman fakes resistance to enhance his and/or her (psychological) excitement. This is not so much common now. But not so long ago, (I hesitate to put down any explicit time, but definitely within our lifetime) the majority of consensual sexual intercourses would look like criminal r*** according to modern western feminist standard. You get a hint from the early history of JAV (VHS era) the only words you ever hear out of the vast majority of JAV girl is やめて yamete (STOP!). Any girl who is fucked without pretending resistance and suffering is automatically labelled a 痴女 slut and (for a JAV girl) close to the end of her career. Cowgirl 騎乗位 back then is almost unimaginable. It's kinda related to too-noisy/fake moaning during sex (another recent thread). Definitely today it's out of fashion.
The problem is NTR is a term used for all types. Covering both the type that I perosnally feel is disgusting, I mean I feel so strong about it, that I think death penalty can be justified. On the other hand, it's a man's most primal instinct, to make as many offsprings as possible, nedge nedge wink wink: determined seduction technique. Of course I am not making broad justification, but leave that many things are rather subjective.
One more point to consider: when DMM/Fanza release their sales and search stats, sometimes they provide break down the data by customer's gender and age group etc. One point that surprised me quite a bit is for female customers NTR ranks either top 1 or 2 in terms of search words (which as I remember genre keywords also compete with idol's names for top rank search word) so it's very remarkable female customers's top genre is NTR which include what I call misogynic r***.
