I've been itchy down there for a few days, but there hasn't been any weird dishcharge and it doesn't hurt when I pee. It has been smelling a bit stronger though. I haven't had sex in over a month and I always pee after and we used protection so I don't think it's and STD. Maybe a UTI? I use a hairbrush as a dildo and i wash it every time, could it be that? Should I see a doctor?
