It’s not merely about big anime tiddies for me.
2D women were created by men for men. They have personality traits 3D women don’t even know exist, like reason, loyalty, and purity. I’d marry most any 2D waifu in a heartbeat. I wouldn’t dare marry a 3D roastie without a thousand page prenuptial agreement, if at all. Nothing against 3D women, but they simply can’t compete with their idealized 2D counterparts.
Then there’s the obvious fact that the orgasms I’ve given myself using 3D (because they usually expect sex to just “happen” to them) pale in comparison to the orgasms I’ve given myself using 2D. Nothing is too taboo or shameful for them whereas with 3D you have to play psychologist for 45 minutes before they’ll even let you put it in their ass.
Why would anyone choose the flawed over the ideal?
