Fire Vagina

Alyssa

When I have sex with my husband without a condom, like 10 min later I get fire vagina. Like intense burning that lasts about an hour then goes away. It doesn't happen when he wears a condom. Does anyone have any ideas how to prevent this? Or any ideas of what it could be? I was thinking a sperm allergy? Anyways. We are TTC so just wearing a condom won't help.
