HELPPP

Okay so, my boyfriend and I just recently lost our virginities to each other and I was feeling fine for about two weeks, but recently I started feeling itchy down there and I've been looking up signs of yeast infections but nothing is really helping. I've never had a yeast infection and I'm new to this stuff, please help. We used a latex condom and Idk if maybe that has something to do with it? if it's not a YI then what can it be and also how can I cure it naturally? 😭
