Damn the horror stories. I swear I've been spoiled in my last two schools. Even in Empire, some of my team mates would come straight from doing muay thai and despite being sweaty as hell, they would have the courtesy to put on a fresh shirt/rashie. And my current spot has showers in the facility and no one I rolled with smelled any worse than what you'd expect from a sweaty man.
But for what it's worth, inform your partners about the virtues of hand washing your gear. Hand washing and hang drying extends the life of your gear. Sarkis told me about that when he noticed the fuzzies growing on the knees of my tights. Also, your gear always smells laundry fresh. I usually just threw my gear in the shower with myself to let it soak, after I showered, toss in a bit of detergent, hand wash, rinse, and voiala, they're washed.
Also, having at least one set of gear for each day you train is helpful. So say one day you're lazy and don't feel like washing your gear....you have back ups. Get more than one jockstrap too. Also, budovideos.com has a cool promo called mystery shorts. You pay $25 and they give you a random pair of shorts. Shorts that would normally go for $50 and up.
And defense soap is the ish. Ring worm free since I started using it.
