Interesting enough, I was recently reading a book on Catholic moral theology. The author, a priest, said that there are no positions (in sex that has the potential of conception) that are wrong or bad, and no place that sex must be limited to, speaking to married couples, of course. So the Church still says that anal sex and blow jobs are out, but you could do it standing on your head out in the woods if you want and that’s perfectly fine.

I was thinking this very thing. Folks are not likely to talk to you about rapes, even less so to talk about date rapes, especially if they feel partly to blame (because they allowed themselves to get drunk, etc). But no matter how she might feel about the actual event (if this is even the case) she may feel weird about sex and not even know exactly why.
In any event, she’s allowed to have her own views about sex, and you are not entitled to understand where those views come from unless you’re her partner. She could have been a little more sensitive about how she descrbes positions other than Missionary, but she’s not the only one passing judgement on this verbal exchange: OP has no right to consider her “weird” any more than we should consider people who worship an unseen diety who refuses to manifest himself while demanding complete obedience and unconditional love despite having endowed us all with the ability to doubt…or something.
Get off her back. She doesn’t like that.
She’s free to have her own views on sex, and she’s even free to think everyone who disagrees with her is wrong. But I think drawing a comparison between you and a harlot based on the position in which you have sex with your husband is most definitely out of line.
I agree with othersider - she should not be trying to “put” her opinions on others. Whatever feels good, feels good. And in the context of a one-on-one relationship, outside of abuse or murder, who else should care?
She’s weird. Period.
that should have been othersider
I would agree with with all of this statement except the last part… “I guess for her, sex is for babies only”. I never heard anyone getting pregnant from oral sex! Peace.
In response to the OP:
Yes, if done well.
That would explain the Catholic couple in line at Genuardi’s the other day. 
It happened two or three times, and I know that at least one of those times it was coochie juice rather than ass funk, but I really don’t know as that makes it any better. And this was while they were engaged, fercryinoutloud.
I somewhat agree, until I considered that “sluttishness” also factors in a lot with what a woman or man allows to have happen to them sexually. If there’s little or nothing that’s off-limits, makes you uncomfortable, or that you consider private, that’s EXTREME slutty behavior. Not healthy, not sexy, not safe. For my money, anything that involves overt humilation, degradation, inflicting wounds and uses fecal matter would be right up there on the list.
I think we can all agree that some sexual behavior isn’t emotionally, mentally or spiritually healthy, irrespective of whether its homosexual or heterosexual, or involves multiple partners or even inventive masturbation. A little slutty behavior – as with a little prudishness – goes a long way. “Moderation in everything.”

Why don’t southern baptists make nasty standing up?
People might think they’re dancing
I can’t think of any sexual positions I’d call slutty unless the description ends in “…in front of a live studio audience”.
She might change her mind when she finally does get pregnant, and discovers that having hubby on top can be uncomfortable even without a full meal beforehand.
I have thought long and hard about sexual positions, and I have come to the conclusion that it is GOOD to think long and hard about sexual positions, and that none is sluttier than any other, if it’s a position that actually permits sexual intercourse.
Nonetheless, I will consider this matter further.
Perhaps you’ll have to experiment on a willing participant in order to come to a conclusion. 
Good luck!
Gah, you beat me to it! Except the version I know involves a nice young ultra-orthodox Jewish couple who go to a premarital counseling session with their Rabbi. He brings up the touchy subject of sex, and assures them that having sex with your spouse is a mitzvah, a good deed. Married couples are supposed to have sexual intercourse, and enjoy it too!
A few months later, the young husband nervously asks the Rabbi if he can speak to him. He’s so red-faced and stammering, that he can’t even get the words out. The Rabbi finally figures out that the young man wants to talk about sex. He asks him “So, things are not going so well in the bedroom?”
The young man says “Just the opposite! It’s great!”
The Rabbi says “Good! Be fruitful and multiply. But what did you want to ask?”
The young man is too mortified to answer. The Rabbi reassures him that he’s been a Rabbi for a long time, and he’s heard everything.
Finally, the young husband blurts out, “Is it okay if we do it with my wife on top?”
The Rabbi laughs and says “Yes, yes! It’s just fine!”
The young man then shyly asks, “well, what about side-by side?”
The Rabbi says “Certainly.”
The young man, emboldened, asks “Doggy style?”
“If you like.”
“Standing up?”
“Absolutely not!”
Shocked, the young man asks "But why not?
“It might lead to dancing.”
Disclaimer–While it’s true that ultra-orthodox adults don’t touch or dance with members of the opposite sex unless they’re married to them, I have no idea if a married couple is actually forbidden from dancing with each other. It’s a joke, okay? ;j
