My Diet is mostly just plain cooked chicken and steamed veggies + Multi Vitamin, Meds & a Metamucil, I drink heavily about twice/thrice a week.
All my Material is from ExHentai, or Artificial Academy if I feel lime playing.
I prefer Watosato (Mediaron! my favorite) / Hannama (Doya Anal my favorite) works.
My technique? Furious masturbation, no tricks. Just an intensely high-energy flog. I try to chain them together as it becomes much harder to fap after all the energy and adrenaline is sapped from your body.
If your going to try any of that, let me warn you, I think I;m slightly M, so it might be painful, I don't really know.
