@uncutaussie: Yeah, damn, 6.4 girth is REAL nice...D'Oh! I got hooked by a "compliment fisher" again.
To the original OP, You and I have the exact same girth. I definitely don't feel 'huge', but it's big enough to make an impression!
I wasn't always this girthy either, I used to have what some might say was a "pencil dick": long and thin. My fiancee knew me back then too, and fucked me back then, and she said to me the other day that she noticed a difference between then and now!
We decided that it was because I get "more aroused" now with her
than I did back then, but that's only partly true. I attribute it mainly to the dick-exercises I've been doing!
Anyway, back to the point, 5.75 girth is thick enough now that she won't even consider anal, whereas before she might have...Shows how much difference a small change in girth makes! I'm not that crazy about anal, but that's at least an example of how there could be drawbacks to having really "huge" girth.
(That isn't to say I don't still want it!)
