Itching vagina

lola

I got a new partner, and we just had sex for the first time. Immediately after sex was over I started feeling tingling on my vagina, about 2 hours after I got home my vag became more irritated, it’s now the next day and I’m itching like crazy, my area is swollen from me itching it, and I have a lot of thick white discharge, is it possible for symptoms of a infection or std to start right after sex?😥😥😥😳😳😳
