i am professional photograther my girl friend wants to put pictures of her in her underwear on social media sites like facebook?

If your gf wants to be a lingerie or bikini model, posting these pics on FB or IG are the worst things she can do for her career. Nobody will take her seriously. If you were a professional photographer then you'd know that the only people who should be seeing her pictures for now are actual agencies or magazines, not social media. Social media is full of a bunch of teenagers who will do nothing for her career

No. As long at people know there's a maturity warning on the photos, there should be no problem. You can also help her find sites that go towards models like the kind she wants to be to get more recognition.

If they are reported for nudity, they will likely be removed. It seems as though your girlfriend is just looking for attention...

if she goes into another career eventually, she may secret those pictures -
