I don't know what there is to hide about not being circumcised. I don't have much foreskin though.. well, I don't think.
I can't do the catching method anyway.
I have never compared my penis to anyone elses... I don't intend on it either. There is/was a site called something like foreskin.org.. the one time I visited that site I did look at the photos. My penis is nothing like that. Some of the photos had a lot of foreskin. Like, the head of the penis was still covered even while erect. My foreskin more or less disappears when erect. I do have enough to make masturbating without any lubrication good.. although I don't exactly have problem in the natural lubrication department.
There, now you have a little more information than you probably wanted to know. I'll leave out my measurements.. I have no idea how to measure anyway.. there seems to be not set way.
