What Causes ED With The History Of Lyme Disease And Anal Fissure?

Question : Hey Doctor, I have a serious question in regards to Erectile Dysfunction. I've read many things that may cause ED in which I have a few symptoms from what I've learned. I would like to know which one of my symptoms would most likely cause ED. My symptoms are Lyme Disease from a tick bite I got in October 2014. I also have an anal fissure since 2007. I also had a stent placed in my penis for a week after having Kidney Stone surgery in the month of September 2015. I was diagnosed with high cholesterol two weeks ago. Other than these ailments I'm very healthy. I workout every day and have lost over 50 lbs in the last 6 months.

With that being said, the only time I get erect is when I masturbate. And I can still feel a dull pain from the stent that was inserted into my penis when I masterbate. I don't get erect from visual attractions or aroused by touching since early 2015. The urologist that performed the kidney stone surgery told me as long as I can get a hard on during masturbation I don't have ED. He examined me for prostate cancer as well which he said was negative. Since this surgery I've had leakage issues after I urinate. I'm lost for words but I'm hoping this can be cured without surgery or side effect pills. Your input and help is greatly appreciated.

So basically, you are saying that my main concerns are Lyme Disease and High Cholesterol? And yes, I get very good hardness from masterbating. The stent is like a catheter in which it keeps the urine vein open after surgery to prevent infections. The urologist explained to me that there's a flap that shuts your urine off which may have been altered due to surgery. However, I still have a dull pain when I masterbate and the last two times I tried to have sex I couldn't get hard. And when I did get hard it would get soft withing 2 minutes. That was back in early January of this year and November of last year. I also lost my girlfriend back in September of last year. Btw, I'm taking fish oil pills for the high cholesterol but I don't know what to do for Lyme disease. Any ideas to get me straight would be greatly appreciated.
