Sperm allergy?

Okay so recently my husband and i decided that we wanted to conceived our first child. The problem is that when he came in me for the first time, the outside of my vagina (my labia minora) began to burn intensively. I checked on the internet and i saw that it could possibly be a sperm allergy. However, it wasn’t the inside of my vagina that was burning. And when he came in me, I just finished my treatment for a vaginitis and I was still a little bit sore from my itching. I’m really concern that i will never be able to conceive “naturally” if i’m really allergic to his sperm and this depressed me a lot😔 i don’t know what to think anymore.. His sperm already ended up on the outside of my anus and my vagina and nothing happened! Also when i swalloded his cum nothing happen to my mouth or throat. Do y’all think it could be a sperm allergy?
