Reaction to sperm

I’m a carrier of the HLA mutation. My boyfriend recently started ejaculating inside me, and separately (but coincidentally?) I’ve had a bad flare up the past month or so. Has anyone had a reaction to sperm like this?

We tested him a couple years ago, and he had a pretty high mycotoxin count. He’s done some detoxing (but not enough to my liking), but that’s a separate subject.

Thoughts?
