itchy down there??

Me and my boyfriend have had a LOT of sex lately and maybe 2 days ago I became itchy down there. We used condoms and I'm not as moist as normal down where I need to be. I figure that's why I'm so itchy but I was wondering if some of you could guess cause or help me figure out how to make it go away? Nervous and would love some relief right about now. Thanks Ladies💕
