My Boyfriend Always Satisfy Me With Sèx But He Doesn't Kiss Me

Right now am facing a serious problem with my fiancee. We are dating for long time and having nice time together. He can sex me from morning to night but to my greatest suprise he dont want to have a kiss with me. He use to told me he never kiss anyone in his life and he want to remain like that. Am so worried bcoz I want to test the flavour of my man lips. Now the problem is any time I demand to kiss him, he would just tell me he dont want it and am seriously in need of it. So pls help me and advice me as usual on how to solve this problem that is giving me sleepless night. THANKS!
