I have mild phimosis, i can retract the foreskin when flaccid but not when erect. i was going to visit the gp for a diagnosis but due to the nature of my condition will i have to show the doctor my erect penis for a full diagnosis?

For this complaint it is better to see a Urologist and you dont have to have an erection to be believed. Some times gentlypulling back the foreskin all the way back using cortisone cream then pulling it back over the head over several weeks will stretch it. Pl make sure not to leave it back but all the way forward when finished. Other solution- circumcosion by a Urologist. Good luck
