26, and having bladder problems already?

Well, I'm no stranger to bladder and bowel issues, as I suffer from IBS and have had multiple lower colon scopes done. As a teenager I had an issue accidentally had my urethra nicked during a routine pap smear, ( Dr didn't really explain what he was doing, and I was suprised when he went in for a swab), leaving scar tissue, which in turn left me in an odd predicament of not having a straight urine stream, meaning if I don't wedge TP between my legs when I pee, it will spray everywhere. It caused me to have a bit of shy bladder and I would hold my pee way too long during the day, if I wasn't home. Now my bladder holds too much, and I find it hard to start peeing, sometimes I have to massage my bladder, and then I finish too early and have to sit 5-7 mins to wait for more pee, if I get up too soon to wash my hands etc, I almost pee myself and immediately have to sit back down. I plan to go see a different utologist as the last one didn't really help, ge tried to widen my urethra, which stretched right back. Just wondering, aside from the odd pap smear I had, if anyone else has problems urinating like that? And what they can do to fix it?
