Hi Cherie, doing the intermittent cath thing without being able to see is a bit daunting at first, but you'll soon be able to figure it out by touch. I use a male FR 14 catheter because they're longer and have (for me) the right amount of rigidity. I don't use a lubricant and don't cleanse the area (just make sure my hands are thoroughly washed). With the male catheter I have enough length to cath from my chair, although depending on the bathroom layout, sometimes need to attach an extension tube. I usually scoot as far forward as I can in my chair, lift one leg at a time off the footplate and dangle each over the side, then feel with one hand for the right opening (stretchy pants with elastic waist come in handy here). I'm fortunate that I can "feel' when my bladder needs emptying, but usually try to cath at least once every four to five hours anyway. I have had some instances of UTI in the past, but I can't say it's really been much of a problem. Hope this helps. Please feel free to e-mail if you have more questions.
