He asked for a nude

Me ams this boy were talking as friends nothing more. Today he sent me a picture and I saved it as a joke and he said now that he sent me a picture with his shirt off that I had to do the same. Like boy I don't even know you. So I deleted his picture and told him that I deleted it and that he wasn't going to get a nude because I only thought of him as a friend and he gets mad saying that if he sent a picture that I should do the same like BOI I DIDN'T ASK FOR A PICTURE. So we had an argument and he keeps asking why I'm mad. I told him he's trying to pressure me into sending him a nude (He keeps saying he's not). Like boi gtfoh. I just blocked his ass because I don't have time for that.
