Burning while peeing..

M

My fiancé and I had sex 3 times back to back yesterday morning - it’s now been a little over 24 hours and suddenly it burns to pee. There are NO other symptoms of a UTI (I’ve had them before and it never burns to pee, just uncomfortable and constant need to urinate). It feels almost swollen down there? I’m thinking it’s because the first 2 times I was wet/lubricated enough and the 3rd time wasn’t enough. I’m thinking maybe it was just too much friction? I know some women get small tears during intercourse and peeing burns the tear if it touches it. I do not need to go get checked for STIs or STDs, my fiancé and I are in a 110% committed relationship, so I know I have nothing to worry about there, plus it wouldn’t show up within 24 hours anyways. Just need some advice :)
