Itchy urethra

Desrea

at first I thought maybe I had a UTI? Or maybe a yeast infection... but my pee hole itches like sin, and it has now for over a month. sometimes it's absoulty unbearable, and sometimes manageable. I've tried Vagisil. it seems to relief it, but dosen't get it gone. it always comes back. I do not have insurance to see a doctor, so I need to know what it may be, or what I can do? Anyone experience Any thing similar? lmk! thanks in advance!
