How would you persuade her to see it my way?

My current girlfriend and I have decided to take our relationship to the next stage; we have been having sex over the past month. One time when I went down to orally stimulate her (I enjoy doing this, from my past relationship) she stopped me, she is against that form of sex. She says she thinks it’s dirty, I respect her decision but is there any way I can persuade her to let me down there I love eating pu$$Y.
