I don't worry about MRSA... or sweat for that matter... or even the other secretions which can be pretty profuse.
It's the other bugs, the garden variety ones, that will migrate from one orifice to the other ones in close quarters, getting wiped around by that big chamois wiper and assisted by whatever lube I'm using. Even if I did take a shower immediately before riding (which most of the time I don't - a thorough @ss-wiping with a damp washcloth usually does it for me when I'm starting a ride in the early morning - sorry if that's TMI
)
I'm not easily grossed out, and I am really relaxed about bacteria (if that video I linked to didn't already give you a clue). I think most of the hype about bacteria these days is just silly, and actually hurts people's health by (1) killing beneficial and balancing bacteria, (2) promoting resistance in "bad" bacteria, and (3) exposing us all to harsh and toxic cleaning chemicals.
But I do not re-use underwear without washing them. That just does gross me out.
ETA: PS, yes, sunlight (UV) is a powerful antimicrobial. Just turn your jerseys inside out so they don't fade too badly, and don't leave your things in the sun for hours after they're dry, as the UV will also degrade the chamois.
