A guy wants to buy my nudes

Hey :)

So I’m not sure if anyone can help me with this topic that feels extremely taboo, but a guy dmed me on Instagram asking if I want to sell my pics to him.

I don’t know who he is but he says he will pay for any photos and we can start small as in not full nudes like it doesn’t even have to be underwear, should I do this or not?

I’m a broke student lmao and could use the money or gift cards but I don’t know who this guy is and don’t want anything bad to happen, what do you guys think I should do?

Also how can I increase the validity of this guy he told me his name and where he lives but I don’t know what he looks like.
