What Is The Burning Sensation While Urinating And Itching Inside Vagina?

I have been noticing that I have a very slight burning sensation when I urinate and also notice that the area around my urethral opening and inside is itchy. I also notice that the area inside my vagina is itchy as well. It is most bothersome when I wake in the morning and as the day goes on or after a shower it improves. I am married and have had no other sexual partners and my husband and I are faithful. I rule out an STD. any thoughts?
