My wife [39F] won’t let me [43M] come in her mouth anymore.

I’m a salvia producer for a large pharmaceutical company. My wife is a dentist and although she likes oral sex, she says that my job (and I think it’s the name and association) makes her uncomfortable with the idea of me coming into her mouth. She used to be okay with it, but now she isn’t.<br><br>Not sure what to do or how to convince her otherwise. Do you have any advice for me?
