Help, allergic reaction or yeast infection??

i had sex yesterday and let the guy cum all over me down there but not actually inside of me. today i noticed that my labia are sore and very swollen. they feel huge and warm to the touch. has anyone else experienced this? is this a really bad yeast infection? (photos below)

i dont think this is caused by yeast infection

any idea what it could be from? i dont have any other symptoms. no discharge. am i just allergic to his cum??

did you use any lubes or gels!?
it does look like a reaction of some kind.

we used lube! maybe im just allergic? i never checked to see which kind he used though

possibly or iritation from friction!
maybe have a bath with some tea tree and wear loose clothing after! ice packs may help!
