I’m a bloke and have been doing Intermittant Self Catheterisation for quite a few years. Not much fun at first but you do get used to it and it gets easier. You will get a bladder infection, it just happens and don’t feel guilty. My doctor allows me to keep penicillin at home to treat it, just pop into surgery with urine sample to be tested. Get some more penicillin on repeat prescript. Guess about 3 infections in about 5 years.
Little disposable plastic bags to put used catheters into is a good idea.
Try to get a bag to put catheters in when you go out, sort of big make-up bag. Compact catheters are very useful if you have to go to a meeting etc and need to take somwe catheters, not too sure if women get them. Male catheter is about 14" long
If going out discipline yourself to do an ISC. Aldso develop a routine then life gets easier.
Never tried Botox. Also LDN helps to make everything a bit more controllable
