Pinched Look on Upper Shaft

Hey bros, I’ve been PEing for a few months now and I’ve made some gains, about .25 in but I’ve noticed I’ve seemed to develop and unusual shape to the upper shaft closest to the glans. I use a vacuum stretcher and it seems that right around the area where the glans cap covers that part of the shaft, I’ve developed what almost looks like a pinched shape. I guess you could call it baseball bat shaped. It’s thiner at the top inch than the mid to lower shaft. Its only noticible when flaccid, everything looks normal when erect.

Before PE, I was pretty much uniform from tip to base with only a gradual thickening to the base but now it looks a little weird being noticeably thinner toward the head when flaccid. I can’t tell if I’ve just increased some mid and base flaccid girth and this area hasn’t developed much or if this is a result of that area stretching the most and leaving it thinner in appearance. The skin also has a slightly lighter tone in that area also, which I wonder is from the glans cap? Has anyone else had similar experience? Any way to correct it?
