I would definitely discuss using this product with your physician first. You don't need a prescription, of course, but I think it's good to determine if this is the right product for you. I used external catheters for my grandfather for a year before he switched to a Foley cath, and our physician helped guide me through the process even though we did everything at home. (A visiting nurse manages the Foley catheter.) Size is measured by girth, not length. We initially ordered a couple in various sizes and determined which was most comfortable, and then ordered a case in that size. It should be comfortable and stay on. You definitely don't want one that slips off, but neither should it be too tight. You will know the right size when you find it. External catheters worked very well for my grandfather for quite some time and really improved his quality of life. Just make sure to find one that is comfortable and use the right products (prep and removal wipes), and maintain really good hygiene. Good luck!

No, you don't need a doctor's recommendation. For sizing find a sizing chart to print out and use like this one: http://www.urinedevice.com/pdfs/sizing-chart.pdf or buy several sizes the first time.
