Day 6 (7-8 days). What makes it easier is not sending energy down to the dick in the first place. If too much energy gets sent down there, it can collect there and build up pressure. This pressure is felt as a fullness in the ejaculatory back-plumbing. I do not feel that fullness one bit. It's been 20x easier doing this than previous times. Gee I wonder why.
By the way showing me pictures of women will not tempt me to masturbate any more. I'm not lying. This is true. First, I only find a small percentage of these pics to actually be attractive. Secondly, with this buildup of sexual energy I've noticed that if a picture arouses great lust (the picture has to be reallllllly nasty just the way I like it, but not in a way that grosses me out), the resulting feeling of energy from it seems to be evenly divided between my heart region, solar plexus region, lower gut region, and the penis. Hardness barely occurs, or comes in small spurts. Third, I prefer masturbating to videos anyway, but even the videos get the same result now. It seems I have to deliberately intend to move into my default masturbatory state to properly jack off to porn now, because it isn't automatically stimulating me in that respect.
