My wife doesn’t give oral /u/squashinghy1 Sex

I have very clean habits. I shower two times a day. Clean my geintals with soap before having sex. Our foreplay involves a lot of me playing with her body and making sure she is pretty wet. I also perform cunnilingus to her regularly and it lasts until she starts pushing me away. Even after this my wife doesn’t give me oral. It has been 4 years since we are together. Despite offering to do anything in return, the max I have got is a kiss on my cock. She says she doesn’t want any of my juice in her mouth. Oral is very important for me. What can I do to convince her? Are there people who had similar experiences? How did you overcome the situation?
