Tingling lips and tongue

I've recently started to give my husband the big finish to blow jobs but have found that for a short while afterwards my tongue and lips tingle. I don't have a reaction to his cum anywhere else so I don't think it's an allergy. Does anyone else get this or know why this happens?

Are you using any lubes/delay sprays/spermicides? It could be an ingredient in a product that you’re using that’s causing a tingling reaction. Even his body wash or soap could be the cause. These are all things I’d rule out first.

Prolonged sucking increases the blood flow to your tongue and lips. It’s just the blood flow returning to normal. Nothing to worry about 🙂

No lubes etc although he showers nightly so maybe his soap. Also it's at the end if sex, so maybe it comes from my own body wash? I was just worried it might be an allergic reaction, could you imagine going to a & e to say my lips are swollen from my husband's cum?!
