I have a wife that is anti oral sex with me. I do her, but she will not reciprocate. That said, it's a taste thing. I have suggested flavoring ideas (use your imagination), with no avail. My advice openly communicate, respect her wishes and remember that ultimately these are all physical expressions of love and wanting to bring pleasure to your partner. Sometimes we have to be willing to give up what we would like, so the experience is a good one for them. Good Luck
