a Sting In My Throught After Swallowing During Oral...

Here's the deal, people:

i really like to go down on my boyfriend. I swallow every time he cums in my mouth, have been doing it for a while, and all was fine. But recently, I seem to get this stingy feeling down my throught after spending a lot of time with him and having sex (including oral), so I think it might be because of the swallowing thing. It isn't very bad, just a bit annoying.



Anyone ever had this before? Any advice regarding what could help?



Thank you to all!
