Is there such things called crabs

is there such things called crabs I've been told there like flea's what are they because I've got a friend who might have crabs because she shave's and she itche's down there like mad

yes, crabs are real
there tiny little creatures that stay on your pubic hair
however
just because your friend shaves doesnt mean she/he has crabs!!
a lot of people itch after shaving because they dont use shaving cream
usuing things like soap, water or nothing to shave with will cause you to itch like mad!
so thats probably the reason for the itching
if they have no shaving cream, conditioner can also work to shave with
youll probably be able to see crabs (as small white dots)
if they can see any then they can be easily gotten rid of
just go to a pharmicist and ask
but its likely due to shaving without shaving cream

yeah crabs exist they are microscopic parasites that infest pubic hair

Yup, what erasmus27 said
