Urinate frequently with no pain no burning?

Overactive bladder? I am not sure how long have you been experiencing this trouble, but overactive bladder is a possibility. Utis often come with burning/urgency/frequency, change of urine color/odor, and lower abd/pelvic pressure/pain. Since u have none of these, overactive bladder is possible. Also, if you drink lots of fluid--what comes in must come out. Alcohol/caffeine make things worse. Consult doc. Good luck.
