On the receiving end and love working for it

Wife is done with sex , but she does take care of my needs in other ways. In our 70's so whose to argue, just do it. My wife seems to have an agenda and that is to see me sucking cock and taking it in the ass with our collection of toys. Butt, before she gets to any fucking, I have to do the sucking. She has a 8 inch realistic dildo in her harness and if I want it in my ass, I have to "Orally perform", to show her how much I want it. As much as I want it in my ass, I do my best to impress. Im able to get beyond a gag reflex and can deep throat any cock that I have ever sucked and several of our dildos. It never fails to amaze her and she has never failed to amaze me with lustful pegging.
I never would have considered any of this, decades ago, but now I crave it, as much as possible.
Do you still get it, one way or another, in your later years?
She says she would be good with no sex at all, but she knows that I still have needs and desires and will do just about anything, to get off.
