A couple highly promiscous friends had crabs.
One got them from banging a girl who banged rockers who banged groupies. No surprise there. His uber hot girlfriend then dropped him for giving her crabs...that was sad since she was pin p material.
Other friend got crabs from banging pretty any female with a pulse.
They were the other two guys in the Three Musketeers of my high school group.
And a big reason that I can talk like I have slept with dozens of women, picked up mucho knowledge from their philanderings.
Most of my high school/college buds were absolute unadulterated male sluts. Pussy was their life and they lived well.
