Blondes

Two women, Alicia and Jane, were walking along the beach, taking a bath in the warm waves of the sea, and basking in the soft sands of the nearby dunes.
They both had wonderful figures and were beautifully tanned. 
After a while Alicia could hold back no longer and she turned to Jane and asked her, "Jane, how comes the area around your navel has blue and red bruises all around it?"
"Oh, didn't I tell you my new boyfriend was blonde?"  

Not only women are blonde.
