Married for 26 years: no blowjobs and no Anal ever!

I love my wife but she is not worried about pleasing me, she never brings anything new to bed. Since I have a strong feeling about family and parenting I've always overcome that over the years. But now I am 50M and She is 47F and it is really bothering me... Why can't I receive oral sex into my marriage, from my wife. I always go down on her (she loves it, having multiple orgasms). Do I have to ask for it, really? In the past, I communicated her about that and she always promised me to change and satisfy me with that, but I am wainting fot the "change" until today. I repeat: I love her and I never cheated on her, but lately I am asking mysef what I am doing wrong...
