I have thought about this subject for many years (as in decades) and what I'd like will sound crazy to everyone, but I am a total size queen. Most of my life I thought my 9x6.5 was small since I'm a grower, but even after I was finally convinced otherwise it still seems average, while my dream size has gotten bigger and bigger over the years.
Now after hearing about jelqing I wish I had done that over the last 30 years; then I like to imagine I could be like 21x12 hard, and probably not much smaller soft, say 18x9. I calculated that if I can loose a pint of blood at the bloodbank just like they take from a 120 lb. woman, then a guy like me could maybe afford 1.5 pints for his cock temporarily. Anyway, you did say these are our dream penises, right?
I know big ones don't get as hard, but a pill from WalMart and a cockring help in that department. It would be heavy so say it'd hang down about 45 degrees when it's hard as it gets, but sticking it up under my low-cut tank tops the head would show in the hairy blonde cleavage of my chest sitting down and I could self-suck by just bending my neck. I used to self-suck when I was young but it was hard on my back and now I can't even get close.
The base would be 3.5 inches wide and say 10 in circumference, while 2/3rds out the width would increase to 4 and 12 in. Just behind the head, width would be down to 2.5 so the head would flare .5 in. per side, making the it 3.5x3.5.
By the way, I love that video on here somewhere of that guy flopping his big beautiful balls around. Guys say I have very nice, big low-hangers and I like the way they slap my thighs when I walk and sometimes fall out of my gym shorts, but I'd take his any day; say a third bigger than mine, so Kiwi size hanging 9-10 inches. I could've done stretching exercises over the years to actually get that.
Now don't get excited, I know what you're thinking and I'll get to that. But I want to say I don't care about being the largest freak in Guiness (well I wouldn't mind it), I would just really like to play with it (and yes, I get off now sharing it with cockworshipers so I wouldn't mind showing it to the world as needed). I've thought of all kinds of new ways I could play with it. In public I think I could have the soft cock wrap around and up my butt to help hide it, and it and those balls would have to be supported by special, heavy-duty briefs in public, instead of freeballing all the time as I do now. I'd have to carefully select my pants and shorts to be as discreet as possible instead of to show as much as possible as I do now, and maybe even have a note from my doctor to sooth the Bulge Nazis (as in police) from time to time.
Ok, you're wondering what good it would be since you figure I couldn't use it for screwing. Well, length isn't an issue with my woman since I'd just bottom out as I do now, but I'd bottom out from any position and could use outside stroking or rubbing between her thighs etc. if needed. We'd figure things out. The more real concern would be girth. But at the head the girth would be around 9.5 in. max (just double what it is now) for it's 3.5 inch length, and as noted it wouldn't be super hard. Seems I've heard of gals here that could take 9 inch girth, at least with some care and "conditioning", and I wouldn't get over 9 inches until near the opening of their chooch. Sure, plenty of gals couldn't take me or gals/guys blow me but if a few could that would be okay.
