I feel stinging when I get an erection after my foreskin's been retracted. Is this normal?

Here are some ... Feeling stinging in foreskin at erection suggests heightened sensation by possible local inflammation from various causes or tightness from over-stretching tight foreskin after "too much" shortening at circumcision or simply from still existing long/tight foreskin with balanoposthitis, etc. So, have urologist take a look so to define what is going on in your penis. Best wish ...
