What matters most to me is results: what makes a woman cum? I’d rather have a dick that was long enough to fill her up, but not so long that she couldn’t get it all in.
My favorite position is woman on top, leaning over slightly with her hands on my chest, grinding down on my cock as thrust upward to meet her and she mashes her clit into my pubic bone. I think I’ve had 100 percent sucess rate making a woman cum that way over the 40-plus women I’ve been with. It might be nice appearance-wise to have a Big Swinging Dick, but I think I’d regret having a dick so long that a woman couldn’t fit it all in and grind down on me like that. So, about 8 inches bone pressed seems optimal for me, because then I think I’d be well up in the cul de sac of most women.
So, I have about three quarters of and inch to go, but my emphasis is more on girth, maybe because I watch too much porn. I think what’s impressive about most genuinely hung porn stars is not their length but their girth. As DLD’s analysis showed, most aren’t extraordinarily long, but I think it’s their thickness makes them look relatively big.
