Allergy

I found out today that I'm allergic to sperm, I'm a virgin but I've given head before but this morning was the first time my bf had ever came in my mouth and it felt like my mouth was burning so later on I went to the doctor and they told me that I'm allergic to sperm I was in so much shock I just tried to get out as quickly as possible and avoided asking questions but now thinking about it I'm kinda freaking out… does this mean I won't be able to have any kids?
