Itchy vagina

Last night, my bf & I had sex (not the first time). It was rough & we used a different type of condom. My vagina is sore (From the deep thrusts) but it’s also itchy & Idk what for. It’s only on the vulva, the itching doesn’t reach inside my vagina. I have no signs of a Uti. What else could it be? Could it have been caused by the condom we used?
