Irritation after condom use, help!

Been using condoms exclusively with my husband for years. Occasionally after sex, especially if we’ve done it consecutive days or multiple times a day I get serious vaginal canal irritation. Mostly itchy, mildly throbbing. Doesn’t seem like a yeast infection but JEEZ what’s the problem. We use non latex condoms. Always keep all parts involved clean (hand washing etc) cause I feel prone to utis/irritation. Dying for some help trouble shooting this, tired of it. Want sex without consequences 😅
