Criticisms first ...
[hide]If the question is, "What do you think your girlfriend would think if she found out you watched porn of women who are the same race as she is?", then I have to agree that it's a pretty silly question to be asking. I mean, at the very least it is an unnecessarily complex question: because you could have asked instead, "What do you think your girlfriend would think if she found out you watch porn?", period, and left it at that.
But if the question is directed to non-Japanese men (e.g. white, black, hispanic) who do not live in Japan, then it's not quite as silly as before ... though it's still pretty silly, I suppose. ^^; Because you're now asking us, "What do you think a girl would think if she found out you had a fetish for a certain race?" And once again, that isn't really a big deal, and it's not specific to Japanese women or to men watching porn videos.[/hide]
Anyway, now on to the answers.
To the 1st possibly-asked question: it's human nature, whether you're a guy or a girl, to feel a little hurt if you discover that you alone aren't good enough to fulfill all of your partner's sexual needs. However, I think every woman on the face of the planet can do herself a favor if she internalized this lesson about the male psyche: men like variety. Period. [hide]It's why most porn collections grow without end. It's why most men wouldn't stick to downloading only one artist's (hentai) or JAV model's (porn) stuff. It's why adulterous men commit adultery in the first place. (Not defending adultery: just explaining the core rationale behind it!) Men get tired of the same thing over and over and over. (Maybe women do, too, I dunno, but definitely men do!)
So if a woman learns this, and if she is remotely intelligent, she should then be able to figure out for herself that:
(a) her man is still more than satisfied with her. He just needs to look elsewhere sometimes.
(b) if she forces him to be with her all the time (e.g. she burns his porn collection, forbids him to look at other women, etc), then even the most faithful of husbands will get really bored with their wives. She's not doing herself any favors to do this to him. If she wants him to stay faithful, she needs to let him look at fantasy-women. Otherwise he's going to go after real women.[/hide]
To the 2nd possibly-asked question:
Some people are racially indiscriminate when it comes to sexual attraction, but I don't think most people are. I think most people at the very least have certain races which they find less attractive than others, for various reasons; and I think many, if not most, people furthermore have specific races to which they are attracted.
Some people think that sexual discrimination on the basis of race is wrong. Others believe it's natural.
Putting 2 and 2 together, I feel that if a woman who thinks this behavior is wrong pairs up with a man who practices this behavior, it's for the best -- for both of them -- if she finds out about it and either one of them changes or else the relationship comes to an end.[hide]
Let me put it to you in a personal way. I think half-European half-Asian girls are super, super hot. Behind them would come (just going to give one example) white girls. Behind them (just going to give one example) would come Native American girls. Is this racially discriminatory of me? Sure! By definition: I am discriminating (i.e. making a distinction between two or more things) on the basis of race! But am I doing it to determine who I can be friends with? Who I can work with? Who I can live with? No: I'm solely doing it on the basis of "whose face could I wake up in the morning and kiss and whose face could I not?" Period.
So let's say here I am, and I'm dating the woman of my dreams. She's half-Japanese, half-German. She's gorgeous. Beautiful half-n-half facial characteristics. Nice big German boobs. Beautiful Japanese silky black hair. On and on the list goes, right? She's my angel. She's my everything.
Now, let's say she discovers my feelings about which races are most attractive and which ones are least attractive. And she says to me, "You're a freak!" because she's creeped out that I like Eurasian girls best and she's Eurasian herself. You know what? She's fucking dumb, then! and good riddance! Who the fuck would get angry to discover that their man finds them most attractive out of all the women on the planet?
Let's say instead she says to me, "You're racist!" because she's weirded out by the fact that I sexually discriminate on the basis of race. You know what? She's 100% within her right to feel uncomfortable; but so am I. She doesn't want to date a man who thinks certain women in certain races are less attractive than others, and I don't want to date a woman who doesn't accept that. We have very different ideologies, and it's best we let each other go.
But you know what? I don't think most girlfriends would respond like that. If anything, her behavior would probably be very similar to what we described earlier for Question #1's answer: she'd probably feel like she has to compete with these other women, and it would probably alarm her that they're all Asian supermodels: not because of their Asianness, but because being the same race as her means that she's got one less ace up her sleeve with which to win back my heart.
And so what would I say to her in that situation? Same as before (for Question #1): I'd make sure she understood fully that I love her more than life itself, and we'd talk about it, and see if we could come to a mutual understanding. Maybe I'd give up porn for her? Maybe she'd accept my porn stash? Who knows. All I know is, we'd talk through it: because this concern's a lot more legitimate than the stupid ones proposed above.[/hide]
