Can too much sex cause this?

So I recently started sleeping with someone and we have been having like an insane amount of sex. We don’t use condoms which is dumb in general but I’m clean and I’m pretty sure he is clean but also hasn’t been tested since his last partner who was a close friend of his. Yesterday my vagina started itching. It’s not like an uncontrollable thing but it is definitely a thing. This happened before with him as well but it went away. Can this happen from too much sex? Or maybe I’m allergic to semen. Or maybe he isn’t clean and just thinks he is. Idk asking for some advice.
