You just have to be really persistent with him. The same thing happened to me, and I got the photos I asked for. He even fucked me when I traveled to NYC, and he's straight, but he likes trans or femboys with big asses.
He's a great fuck, he's really tall and big but he doesn't have that enormous dick size like in his photos irl, He edits his photos; if you zoom in you can see the elongated pixels, but he really does have a nice dick, I don't know why he edits it more.
Y'all should ask him for the gay videos because he has videos and photos of himself fucking gays.
