TattooedTaurus

Hi there, I'm 37 and am in need of advice from a medical professional if possible. Ok my situation goes like this. I have always noticed what I considered an abnormal growth from my circumcision line right in the middle of the shaft of my penis. The lump looks like cauliflower in appearance and then a slight raised line that travels vertically down to the bottom of my shaft to the scrotal area. I always thought there was something wrong with me as I have always had this as long as I could remember. Well in my curiosity I had this checked out from a dermatologist as the cauliflower appearance resembled HPV(from what I read) but had never been diagnosed with this. The dermatologist ruled it out because one quick look and he said this was not HPV. So he didn't do anything for me. I was still wondering what this was so I saw my VA doctor and he called it" redundant skin" from circumcision and said it was "normal". He said the line was where we come together when we are forming as a fetus. Well I can't leave well enough alone and I wanted to remove the cluster of skin on my circumcision line so I tied some line around a bit of it to try a ligation. Well it caused a small scar there, and I was wondering can this trauma interfere with erectile function? I have been having sharp pain in my leg, buttocks and foot in my left side and this started about 2 months ago, diagnosed with sciatica, and here recently I have been having trouble maintaining a full erection. It coincided after I tried my little" experiment". What could be causing my ED? I tried the ligation because frankly I'm quite embarrassed with the appearance of the underside of my penis. Now looking back I have discovered that this could be very well something called my raphe? I regret doing the ligation now because I should have done more research. Can you please give me any information to put me at ease and what I can do to address my inability to achieve a full erection? I've never had any problems at all before with this issue, it seemed to come on very suddenly. I do masturbate quite frequently and now I cant seem to get myself sexually aroused with any visual material. Thank you and any opinions will be greatly appreciated.
