Might be worth trying one of the Bike-style jockstraps listed with spandex instead of latex to try and isolate any material sensitivity issues.
MRSA is no fun. Anecdotally, a family member had good luck controlling their outbreaks by supplementing with colloidal silver *I'm not a doctor.*
Taking care of older family members been dealing with ringworm fungus in particular and generally being paranoid about pinworm bedbugs scabies and any other possible and annoying hygeine complications. I am repeatedly alarmed reading that this or that cleanser is ineffective (like maybe for general maintenance but never specifically to sanitize) and that you're really just supposed to fry everything at high temps, which is lousy for elastics.
I had high hopes for ammonia, for oxiclean, but no. Teatree oil I would expect to do well and is appealing as I generally use it around the house and the scent doesn't make me cough and gag like most laundry stuff, but you'd have to futz with a lack of documentation on efficacy and concentrations, and possible/probable degradation of elastic and plastics. Plus I have been advised it is bad for appliances for both gasket solvent reasons as well as volatile flammability issues. Pretreating sounds plausible but hand laundry facilities are often lacking, and if I were into pretreating I might own clothing in colors besides black.
I think i'll be ordering in an oxygen cleaner or detergent blend that specifically has an activator. Available in powder only, seems to require presence of oxygen bleach as well as high temps but I'm not specifically seeing all the temperature documentation I'm looking for. The activator ingredients are Tetraacetylethylenediamine (TAED) or sodium nonanoyloxybenzenesulfonate (NOBS), which at temp and with oxygen bleach create the necessary chemistry, peracetic acid and pernonanoic acid respectively. I'm leaning towards Oxiclean Sanitize specifically but need to shop around.

Being low-income and also valuing my expensive elastic socks and underwear (I'm especially mindful of my $100 christmas gifted Smartwool long johns I need to not get frostbite, among other bicycling gear) I'm reluctant to admit that some garments are supposed to be temporary. A new jockstrap before every game from the equipment manager I guess. Turnover wouldn't be so bad if good products weren't discontinued, mass production cost benefits weren't wildly diluted with inferior products, or if the products were natural or rayon fiber and biodegradeable.
A bike-style knit mesh jockstrap in cotton/ hemp/ rayon/ tencel/ modal/ latex fibers would be great for carbon, agricultural considerations, biodegradeability, microplastic pollution, flammability, as well as comfort and horniness reasons. I would buy in bulk if the fit were right. black, olive green, unbleached hemp off-white, maybe a super subtle botanical print on the waistband. Just a suggestion.
Also looking forward to fully bio-based spandex replacements coming online, I really do rely on spandex for jeans and trousers to be remotely tolerable. Maybe I'll take up sewing and just pleat everything to death so they can fit my fat gut and I can squat down without first stripping my pants off while I'm busy sloshing all my clothes in boiling water.
Maybe that's why Mad Max post-apocalypse scavengers only wear chainmail and leather jockstraps. Great range of motion and easier to repeatedly steam sanitize to keep at bay all the superbugs bred by ambient body-temp climate and sloppy antibiotics policy. God knows where you can source decent non-nano-particle lead-free zinc oxide sunscreen as civilization collapses into a scorched earth, don't want your butt cheeks scorched as well!
