This position offers a differing angle of insertion for the woman.
I don't think that the name of this position is at all related to the gay pride rainbow. I believe it is just a coincidence.
This might be a good position for the guys out there that
want a woman to lick their toes. It is definitely not
for folks with some of them Stanky Feet. Hoo man, my
friend Jim has some smelly-ass feet, I am absolutely sure
if Jim could get a woman to have sex with him, she wouldn't
see the gold at the end of this rainbow.
