Hello and welcome to HCM.
As an
Urologist, i fully understand your concern.
You're a lucky guy,to have so many sweet girls, flirting around with you.
From your description, it seems, you haven't had a
circumcision,and it's your penile foreskin,that seems to be giving you the pain, with erection.
Anyway, i'd strongly advise you to have a check-up with a doctor,to know exactly what's causing the pain. Circumcision is a routine minor procedure, and that will cure your symptom of painful erections, if foreskin is the cause.
If you've any other doubts,send it as a direct question to me.
Dr.Matthew J. Mangat.
