I am Type diabetic on Insulin for the last 30 years. I also take other medications such as Lipitor for Cholesterol, Coversyl for Kidney Protection, Baby Aspirin to safeguard against potential stroke. I have had quick ejaculation since contracting Diabetes and I don't feel happy in that I cannot hold my climax for more than 5 minutes and although my wife does not say anything about this to make me feel unmanly, I do believe this does not make her feel happy. I went to a urologist who gave me an appointment to have Cystoscopy done for me tomorrow and I am wondering if my quick ejaculation problems which is caused by my advanced stage of diabetes warrants this kind of biopsy. Please help and give me your insight ASAP.
