Circumcision issue

hi guys! i would just like to ask...this has been bothering me ever since i was circumcised..i am already 18 now. Well..it all started when i have watched and seen other guys penises (from porn and other media) wherein i can see that i have a different cut on my penis. In description...the thing is normal but there is a very prominent skin like structure below my penis, i know the frenulum so i am sure its not it and its much bigger than that...its like a flop of skin underneath my penis just below the frenulum. Its actually very sensitive to touch much like the frenulum itself but unfortunately, being it not "normal" from the images i see...its affecting my self esteem and worries me on what really is it. From the time i was circumsiced up until now...i havent had the courage to talk to someone or even a doctor because i am scared of humiliation and embarassment. I would really like to know what is it (i am thinking its an excess of the skin that was circumcised), if there is a possibility for it to be removed and to know and be assured that i am not the only one who has it.

thanks for reading and for the enlightenment!

PS: i have been searching the internet on pictures of different kinds of circumsicion cuts but up until now i cant seem to find one...if you can find one kindly share it to me so that i can "compare" mine. thanks!
