This is far from certain but is one hypothesis. Another one is that, like armpit hair it traps scent molecules (mm mmm!) to make you smell sexy.

In any case, like the rest of the hair on our bodies, we’ve been styling it for millennia (my phone suggested: stroking it, which is probably also true) and probably won’t suffer if we get rid of it.

One practical benefit of shaving pubic hair is immunity against pubic lice!
