A flip flow doesn't work for me either, when i use one i also have spasms with leaking. I only use a plug for a couple of minutes while showering. Otherwise i let the catheter drain constantly. Sometimes i still have some leaking beside the catheter and i think it's from the lowest point of the bladder were urine collects around the balloon. I therefore still use pull ups, but just the ones for minor incontinence. I also have some discharge but it doesn't hurt and the diaper helps with that as well. The feeling of my body trying to dispel the catheter i only had with a latex cath now i have a silicone and i hardly feel it.
The only downside is the smell of the catheterbag. I use a bag only for a day but after a few hours i can smell it. I do have infections but it doesn't hurt, only lets my urine smell awfull, even through the bag.
