There are plenty of reasons to love , the gorgeous, body positive model, author, lingerie and swimwear designer and judge on America's Next Top Model.

Graham embodies a certain kind of modern sexuality that is in your face, unapologetic and fun. She isn't afraid to do a racy swimwear shoot for Sports Illustrated, or walk the runway in her underwear, or use her considerable assets to their best advantage on a red carpet.

All of this, you might think, would mean Graham's sex positivity extends to pornography. Watching porn, after all, is no longer the secret shame it once was. Plenty of people do it, many of them women.

But no. While Graham is happy to say she's watched porn, she's also decidedly not into it. And there's a very good reason why.

In a new interview with Elle, Graham riffs on the very important difference between a sexy swimsuit shoot and porn. After revealing she met her husband at church on "Porn Sunday" (yes, that's a thing) the interviewer puts to Graham that porn is about "owning what you've got".

Graham does not agree.

"Listen, I don't watch a lot of porn, its really not my cup of tea. But I think porn has opened up this door to not just a fantasy, but even an expectation of what people want in bed. And it's not true. And it puts a lot of pressure on women," she begins.

The interviewer then asks:

"Where do you draw the line between women posing for porn, and women posing for something like Sports Illustrated, which is also overtly sexy?"

To which Graham replies:

"For me, I don't do nip or bush. I won't do it. And that's because I talk to numerous young women in high school and I talk to them about owning who they are, and not giving up their sexuality because they have to.

"I think it's important for women to honor their vagina. A lot of us give it up quickly just to feel love. For me, being in Sports Illustrated is saying, love yourself. Be proud of who you are.

"You know, my Lane Bryant ads are non-retouched. You see every lump and bump. Even when I saw it, I was like, 'Well, I thought I was sucking in more than that. Oh well'. It's real. Porn is artificial on so many levels."

She's right. Porn is artificial in the ways it portrays women and their sexuality. Mainstream heterosexual porn is geared towards men's sexual pleasure, and depicts women in a myriad of unrealistic ways.

The least surprising study of all time recently revealed the keys to female orgasm are deep kissing, manual stimulation and oral sex. All of which are not really key features of most heterosexual porn.

So Graham's point, that there's not currently a lot of body positivity for women in mainstream porn, absolutely stands.

And if you're wondering where the body positivity is in a Sports Illustrated shoot, look no further than Graham herself, who proves with her confidence and stunning looks that women who aren't the "norm" can be sexual beings too.

That message is important for every woman who doesn't feel like she conforms to typical beauty standards, who worries the person they like might not like them back because they're not small and perfect. Who cancels on blind dates to avoid rejection, or only feels good about themselves after a few too many wines.

Beauty standards are part of navigating this world. They can make the people who don't fit them feel like absolute crap a lot of the time. When someone comes along who breaks even just a few of those standards it means something to the people who can't see themselves reflected in them most days.

That's the power Ashley Graham is talking about, and it's something she takes very seriously.

So yes, Sports Illustrated IS selling sex. So is porn. But how they do it is very, very different. And that makes all the difference.
