I use the softer silicone ones. When I started using them I started with a paeditatric size beacuse I found it a bit painful and difficult but once I got the hang of it I moved up to the adult ones and I think I am using a size 10 (but don’t quote me on that).
I don’t use the pre-lubricated ones as I found them far too slippery but I do use a tiny bit of KY jelly on the tip to make to easier to slide in but don’t use too much or it is uncontrollable
I found at first I had to use a mirror to get it in. I used a low stool to prop the mirror on between my legs on the floor and sat well back on the loo seat so I was well balanced. Once you have found the right place I found it best to hold the catheter quite clost to the tip and use the fingers of the other hand to part the skin of the urethra opening. Take a slow breath out and glide the cath in… Once the wee starts to dribble out, pause, take a gentle breath in and then just manouvre the cath the last little bit in until you get a good flow.
Take your time. Be prepared with a couple of caths and don’t get flustered of you muck it up a few times. It does take a bit of practice. But before you know it you will be doing it with your eyes shut and wondering what all the fuss was about.
If you find gripping the cath difficult you can get a nifty little grip device that clips onto the cath and gives you a better hold on it. I used it for a while when my fingers were particularly numb. Your continence nurse will know what I mean if you think it might help.
Best of luck and soon you’ll be peeing for Britain
