Circumcised guys have larger FLACCID glans
I think there is no doubt about it. Erect, there is little difference - except cut guys have the more prominent coronal ridge.
But flaccid. Judging by all the guys I have ever seen showering after sports, and by all the pics on the net - uncut guys tend to taper down towards the glans. Pulled back, there is little coronal ridge development, glans are moist and usually a bit smaller to noticeably smaller than the shaft.
Cut guys when flaccid tend to have fairly large and prominent glans, and I think it is more than an illusion. Maybe its because the glans can develop more without being restricted by the skin? Maybe it’s because they keratanise, develop a few layers of extra skin and therefore thicken. What do you think?
