Itchy!

So I searched on this app by words to see if I was crazy, apparently I am not alone! But I am wondering if anybody else present on the app has had this?

Sometimes after I have sex with my boyfriend my vulva area will get itchy! It lasts for a day or two and then goes away... it's not a yeast infection because there's no weird discharge or smell. We are totally monogamous and neither of us have STDs. Just itching around the entrance to my vagina. Anyone else experience this? From past posts it seemed some people have had this happen as well..
