Should I Be Masturbating?

Recently there was announced a new title for the Playstation Vita, called Bullet Girls. Put simply, this is a game that is about young and pretty girls attacking one another, and when damaged lose pieces of their clothing (clothes-degradation). There's also implementation of the Vita's touch-feature, which will be used in "Interrogation" sequences where you, presumably, extract information from captured girls by any means necessary. As seen in the photo below, stripping her down to her underwear and then getting your touchscreen on is fair game.
For those of you reading this and are shocked this is releasing anywhere other than PC, I can assure you that there's nothing 'new' about this, especially in terms of the Vita's Japanese (and soon Western) library. From Senran Kagura: Shinovi Versus, a game also with clothes-degradation and a locker room where you can molest the girl's buxom parts via touch-screen, through Criminal Girls Invitation, a game where you must train your all-girl squad by "punishing" them with gags, whips, and tazers (the girl's making erotic sounds and pleas throughout), and onwards through Genkai Totsuki Monster Monpiece, a card game where you evolve your all-girl cards by stroking your Vita up and down and are rewarded with the evolved card that has the girl wearing less clothing, there's clearly a trend going on here.
I'm not insulting or high-horsing these games (I own all three), but what I'm wondering is exactly what I'm supposed to 'do' with these types of games (silly question, I'm beginning to see). Despite the fact that I've played many of these sexualized titles I've never looked at them as tools of eroticism, but only as interesting import games. Embarrassed and amazed, I giggle and grow wide-eyed at the scandalous moments. But I've never masturbated to them, and what I'm asking myself now is, 'Why not?'

The debate concerning most of these games (and animated pornography [hentai] as well) is the way arousal is initiated. The most common dissent toward hentai, which are rape scenes and 'loli,' or underage girls, can be applied to most of these titles also. Clothes-disintegration, which is initiated by physically harming a character, can obviously be seen as a form of sexual violence, and the punishment sequences of Criminal Girls are clearly trying to capitalize on just that. And not only is loli applicable here, but it is also the standard of these sexual videogames. The Japanese are often (unfairly?) called a 'youth-obsessed culture,' and this is apparent not only in real life fashion but also entertainment media as well, and especially so with pornography both real and animated. Could it be said the girl in the above screenshot looks any older than 14 or 15? Scroll down to the 'Punishment scene' image from Criminal Girls; does she look older than 10?
The issue though, for both myself in regards to being stimulated as well as the general western consensus in viewing these games, is that what these games are doing is only associating with certain taboo sex-acts, and yet are also not these sex-acts. Despite the amount of distributed hentai involving rape and loli, the Japanese still have the same moral view as westerners; sex with an emotionally or intelligently immature person, or forced sex upon another, is wrong. And I don't feel the need to expand on that either; while what qualifies for 'immature' can be put to test, the basic idea is sound. And rape is rape; it's low, it's terrible, and it's unacceptable.
But that's just the thing; despite this same view, this media, which comes so close to portraying these taboos but doesn't, and is therefore published and distributed on a wide-scale, is acceptable. And the reason why is, as every fan of hentai has said, from the non-violent to violent viewers, 'It isn't real.'

Like it or not, Western gamers are about to face the radical content of these once 'Too-Japanese' games on their own home-turf, and soon. Monster Monpiece and Senran Kagura: Shinovi Versus are confirmed for western release, and alongside them is another title called Akiba'Strip: Undressed and Undead which has your character roaming the streets and forcibly stripping females (and males) to discover if they're vampires or not. And I think, from the several negative and xenophobic comments that were delivered Senran Kagura Burst when it was localized last year, that it's certainly time to try and see these titles not as 'Japanese sensibilities,' but as available entertainment, and to approach the 'It's not real' argument and view of animated sexuality with more openness. And maybe, as this blog's title suggests, percieve these games not only as acceptable, but also as the games they really are; erotic stimulants, which is where these games, which are often limited on the gameplay front, succeed greatest.
