Broken hymen or UTI?

My boyfriend and I lost our virginities last week (we used a condom) and since then I’ve had to pee a lot and my vagina kinda burns. However apart from the first day, no blood was passed and the urine isn’t cloudy (the accompanying signs of a UTI). It started to subside but we had sex again today and the symptoms have restarted. Is this normal when you lose ur virginity, or is something more serious happening like a UTI? He has a large dick which could attribute to why everything’s aching- muscles are still getting accustomed. If anyone could help, that would be wonderful. I don’t want to go to a docters unless I have to.
