Dating a wanna be bikini model pin up girl?

so my new gf is 21 .. i am 25... the thing is she has hollywood ambitions.she wants to be in movies and is trying to make it as a pin up model. she has already gotten some supporting extra roles on some pilots, and i think thats great.. if she makes it thats wonderful. The thing is .. i know some pin up models and many actreses end up being nude infront of cameras... She is confortable with her body and thats one of the things i love about her.. however at the same time, as i am confortable with her in a bikini even something as racy as a thong, i would not be so confortable with her completely nude... at least not on film anyway ... I dont mind riskey... maybe implide nudity ... ..but with all the naughty bits covered up .. but actually showing the naughty bits would be totally too much .... .. She has taken some portfolio pictures with a pro and they came out amazaing.. she looks beautiful, but they are basically her in a bra and panties... .. how do it deal with this and keep her from showing everything off.... I like her very much and we have been dating for about 1 and half years... .. ..
