Down-There Sweat☀️💦

How can I prevent my crotch area from sweating?! I've tried all I could think of to at least bring it down a bit (which has been a challenge because my thighs touch), but it still happens. It's embarrassing and it's costing me a lot of money (in terms of laundry) because I have to change my pants and underwear whenever I get home from going somewhere. I've tried trimming my pubic hair -even went as far as shaving it completely, which I HATED- and bought clinincal strength deodorant to apply between my thighs. What else can I do? It's heating up for the summer and I don't want to smell like nasty crotch sweat when I'm out doing the things I want to do.
