TITLE: Me [30 M] with my GF [29 F] of 9 months, she isn't happy with my photography of models, looking to get an outside perspective
POST: So my girlfriend and I have been living together for about 4 months now in our one bedroom apartment in New York City.

Pretty much my only creative or artistic talent is photography.  I got started several years ago, and have been doing portrait work for about 2 years now.  I have a small studio set up in our apartment which I use.

There's a website called Model Mayhem, which is essentially a Facebook for models, photographers, make up artists, etc...  People can message back and forth with one another and set up shoots or castings and the like.

I use the website to message models (men and women) that I'd be interested in arranging a photo shoot.  Sometimes the shoots are outdoors, but if they want a studio environment, they come to my apartment.

My girlfriend is aware of this, and does not like it when I have female models over.  She'd rather me photograph exclusively men or children, no women at all.

I have done shoots involving lingerie in the past, but these are few and far between.  I've never done any shoots involving nudity, nor am I interested in doing any.

I've tried to explain to her that there's absolutely no romantic subtext to these shoots.  The model and I are not "hanging out" or getting drinks or anything.  They're over for an hour or two (if we indeed do decide to use the studio), then I spend some time processing the images, then upload them to Dropbox and send them a link, and that's the end of it.

We've talked about it and she suggested that I speak to women that I know to get their opinion on if they'd be comfortable with the photography going on in their apartment with their significant other, and I figured that's a good idea and Reddit would be a good way to get that input.
TL;DR: 
My girlfriend isn't happy with me having photoshoots with female models in our apartment.  I've explained that's purely business and a creative outlet, and there's no romance of any kind involved.  What do you think?
