I know that usually I get about 97/98% hard. One day I woke with wood and decided to watch porn but not masturbate. I sat there legs apart and it got harder and harder it was amazing. I'm usually 6.5x5.2 but one day I saw I had grown to 6.75x5.2 but since then I never got to that size so I though I measured wrong. But on that morning when I got so hard that I couldn't bend it down at all I was indeed 6.75. And it felt so good. How can I get this hard again? I need the right stimulation.
