What Causes Dryness In Vagina With Frequent Urination?

I'm having a bunch of different symptoms. About a week or 2 ago, I've been having a frequent urge to urinate all the time. There were days that I would have to urinate maybe 7-10 times a day. During this time I was also having sex with my boyfriend and I've been experiencing that I was completely dry. We would then use lubricants to help the situation, but then I experienced a lot of pain during sex. Two days ago, I started having a vaginal discharge that at first didn't itch, but now it does and I'm still feeling very dry down there.
