Irritation On My Vagina

so i have had itchiness around my lips and it is even more itchy right on / by my vaganial opening and it is driving me crazy, (idk if this has any relation but i had sex 2 times last week with a condom idk if that has anything to do with it because i dont think I'm allergic to the condoms ( latex) because when i had sex for the first time last we (first time having sex ) it was not itchy or burning or any irritation so i dont know what it could be )
