I'm an honest 7 inches when I am fully erect, and am only able to utilize 2 inches of my penis when sucking myself because the body is only so flexible. For me selfsucking is something I occasionally do after edging. I would be happy make video of myself but need someone to hold camera to demonstrate because pulling my legs over my head would only allow one angle. Porn sites have extra camera people and that is how they are able to make the video. Selfsucking for me is nothing more than ejaculating in my mouth using my own lips, tounge and suction much like giving another man a blowjob.
