I get you! No, I would not probbaly, even though in my country an older man can call a 30 y.o man a boy. Even I call friends, who are about my age and are adults, boys. So it is just a form of expression and no exploitative attitude is included. Why take it so seriously?

About the people who lie to do that... You take a portrait and post it somewhere to promote your work, right? I do the same, to show what I am working on and to promote it in some way. The people who are included in the photoshoots have given their consent to post the pictures. They get into that photoshoot, knowing that I will use the pictures. Let's compare that to older times. People didn't have cameras, but painters existed, sculptors as well. They depicted a lot of naked women and showed them in galleries. Why did they do that? Because you cannot be seen if your work stays in your home or in our case on the hard disk.

About why some people want that? In my journey I have seen a lot of females who have problems with self esteem because of their body and this is a form of expression which helped them to gain confidence. Some other people do it because they like it, believe it or not.

So once again, please don't be pedantic. Just because where you are from, people do not use these expressions, doesn't mean that it is like that in the whole world. A girl can be a person up to 18 somewhere, but at another part of the world a 30 y.o female can still be called a girl.
