Lotion for Vagina???

Okay so this is a bit awkward but I am in need of some help. I work at a pool and there is an ungodly amount of chlorine and chemicals in there, enough to where after a week of working there my black swimsuit has faded into light grey. So after I rinse the pool water off of me, I always put lotion on to moisturize, but what about under the belt??? I'm really concerned because the skin is always really itchy and irritated and dry?? Any suggestions???
