Swallowing during sex

This happened to me the first time I ever swallowed about 3 years ago, the day after I swallowed my throat was red and very painful like a sore throat, it hurt to swallow.

After that I never swallowed again. A while back I swallowed again but nothing happened but this was a different guy. And I was with a different guy last morning and same thing happened, my throat is killing me right now.

Is this normal?
