I had a medical issue last year that required the use of intermittent catheters. VERY luckily, only for about 4-5 days and have been fine since. Each time it took me about 5 or 6 minutes to work up the courage to stick the thing into my previously unviolated hole. For the first couple of centimeters the feeling is "This is just wrong". The things were about 26 inches long and once you get it in you just have to keep going. It is hard for me to understand how people find pleasure in their use. You feel a bit of resistance and then, the wonderful moment when the steady stream of urine starts flowing out.

It was painful to get the thing out. I couldn't decide between going slow or ripping the band aid off method. I favored slow.

To this day I cringe when I think about it, how I was sodomized by that little straw.

One last thing...the medical people really stressed how your hands need to be thoroughly clean to avoid infection. I bought these special catheters that came pre-lubed and with a sliding sleeve so that you didn't have to touch the part that gets inserted.

Anyway, more power to the people who use them as part of their kink, but it will never be mine.
