Reoccurring yeast infections?

I always have lots of discharge (never smelly) and combined with my physical activity I feel that I'm always super damp down there. Normally after I've been to the gym a lot I will get very irritated. Normally just redness and extreme itchiness. No sores, abnormal discharge, or weird smell. When I give it time to air out (sleep without underwear and just loose shorts) I don't experience the irritation as much. Could it be a yeast infection or just normal irritation? Tips or advise please
