Frequent urination - Maybe TMI

So I always drink a lot of fluids and therefore need to pee a lot too. This evening has been ridiculous though, I went minutes before sex then half way through I felt like I was going to pee 🙈 finished anyway and went after, then within half hour to an hour I had to go again! Definitely not a urine infection as it doesn't hurt and it's full bladder emptying not just little dribbles 💦 don't really know why I'm sharing, just thought it was strange 😆
