Help?? Scented soap

Hey! So recently whenever me and my bf have sex my vagina gets so irritated and dry? Then it gets so irritated for days and i can’t have sex. Even with lubricants, still gets irritated. I’ve been wondering why and started thinking maybe it’s because of my recent soap change?? I’ve been sexually active and never had problems until recently. I was using dove cucumber scented soap and since it’s scented I’m wondering if that’s why. I don’t wash the inside only the outside but I just switched to dove sensitive unscented soap. Do you guys think it’s the soap that’s causing all my irritation or something else?? Thank you!!
