Itchiness in vaginal opening?

💕 Aria 💕

Hello all, for the past few days, especially after urination, I've been experiencing itchiness and irritation in my vaginal opening. The smell isn't off, I don't have any abnormal discharge and I haven't had sex for the past 5 months or so. The itchiness and irritation comes and goes throughout the day and is relieved only somewhat when I sit in the bath. I have no idea what this might be or what caused this sensation. Has anyone else gone through this? Please help
