What Causes Burning Sensation After Urination And Dry Foreskin?

I am a 29 year old uncircumsized male. About 6 years ago I had a chronic throat infection problem and after 10 months of being on anti biotics and many different tests, I started to develop yeast infections. Common for anti biotic use. My tonsils were removed and I havent had any more throat infections. Until last winter I hadnt had any more yeast infections. I got a yeast infection for what I believe to be the cause of me trying new soap and I didnt wash it off properly, cause I was not sexually active. I bought monistat applied it and with in days it was gone. Then this summer I received another one, again not sexually active. I bought monistat and it was cured. Then this winter about 2 months ago I got another one, again not being sexually active. I got rid of it but then I had a mole on my face that was infected and I was put on antibiotics and a week after the anitbiotics were done I received another yeast infection. I applied monistat for a week as I have always done, and this time I cant get it to go away. Everytime I think its gone it comes back. However now it seems to be getting worse. I went to my doctor last week and he gave me Lotriderm. I applied it as perscribed for a week and no difference. So I went back today and he told me my sugar blood test from a week ago came back normal, my STD tests even though Im not currently active came back normal. Today he did some urine tests and more blood tests. I have had for about a week the urge to urinate almost every 10 15 min and it burns when I urinate. I have the dry cracked skin on the forskin of the penis, the head is red, irratated, the meatus is red and too the left slightly raised and swollen. I normally urinate more then most. However more in the past week if that is even possible. I did the Cancadia spit in the glass test and there are legs and strings. I was prescribe 150 mg 1 pill for 3 days of Dilfulcan. Can I ask you for your thoughts?
