" We asked our Welsh teacher, Mr Llewellyn – who is young, to tell us the Welsh sex words. The Welsh word for sex is ‘rhyw’. It sounds like coughing. He said that, in general, Welsh-speakers use English words. When pressed, he gave us a couple of examples to show us why this might be. ‘Llawes goch’ means ‘red sleeve’. ‘Coes fach’ means ‘small leg’. The phrase would be: ‘Put your small leg in my red sleeve’. "
