Girlfriend isn`t a nudist

I have a wonderful girlfriend , she knows I am a nudist and doesn't mind me being nude around the house or going to a resort ( she has been to 3 with me) but, she is shy about her body and never gets nude at all. I tell her it is not about looks . My question is, what can I do to ease her into nudism? I am nude at home most all the time (we live together) and she doesn't care ( as long as I sit on a towel , LOL ) Thanks to all that replies ! Have a great , safe , 4th of July !!!
