wow.... these docs are thinking like the Donk here; deciding to inspect the rectums of female surfers under the guise of "medical research" to determine how some type of bacteria enters their asses.....
just when I thought I'd already come up with every excuse to gawk at, feel up, prod, ie, "study", well rounded, in shape hott chick asses, they outdo me..........
they are surmising that the "in-shape" asses have tighter sphincters than the typical fat ass broad, thereby being "too tight" for the bacteria in the ocean to swim inside their backdoor love ovens.....
I would volunteer, much like a college kid in need of money, to be a "sphincter-tightness tester".... as the most fine-tuned instrument on the planet for gauging a woman's "sphincter tightness" is in between my legs.....
