Thank you for your query at DoctorSpring.com
I have seen the image that you have sent and it looks normal. If you're referring to the part near your tip of the penis, it is slightly red for everyone in that region, and that is due to increased vascularity. I could not see any visible red spot anywhere else in your image. And again the part i mentioned is more sensitive since it is very vascular. In fact the whole of glans is very sensitive and more so in cases of circumcised men.
If there is any other particular spot, you are concerned about, kindly take a slightly more zoomed out picture, or if possible point it out in the picture.
Hope this was helpful,
