Pee burning

Every time I have sex I go pee right after, but two of the times in the last two weeks I’ve gone pee and it’s BURNED. That’s never happened to me before (and it’s only happened two of the times recently but not other times in the same two week span) and it hurts for like an hour after but goes away. If it was a uti it would hurt every time I pee I think, but it’s only immediately after sex it’s been hurting.

I’ve looked it up and Google says it could just be vaginal irritation or sex is irritating my urethra, but what do y’all think?
