itchiness

okay ladies! so after having sex a few days ago I noticed that my vulva area was kind of itchy. I just ignored it and went about my day. tonight, the itchiness became almost unbearable. there’s no sores of any sort or bumps. could this be caused from irritation of not having enough lube during sex? (also keep in mind that my boyfriend and I have sex just about every time we are together with no condom)
