Wookey hole definitely only means female genitalia.
The cave park by that name is just the owners having a dirty joke at the expense of the general public who have to hear young children and parents saying that phrase outright and inappropriately in public.
Another miss used word is '
pussy'. I feel so uncomfortable hearing my mother constantly telling my
cat that he is a ''naughty
pussy''.
''I sexed my girlfriend in her big, hairy wookey hole''
Father : My wife is going to show the kids around the wookey hole this weekend.
Father's mate: What the cave park?
Father : No, her
pussy
Father mate: Oh! ... can I bring my kids too
Father : Sure
''Apparently it is cheaper buying tickets to go inside a wookey hole if you buy them off street rather than through an agency''
