Do most wives crave PIV more than anything else?

Married over 25 years - healthy sex life (3 to 4 times a week) and regular orgasms. When it comes to sex, everything is all about PIV. Oral sex can happen but pretty rare. Anal is even more rare. However, PIV sex is always on the table, and I can have plenty of variety with positions if I want it (and if we're flexible enough!).

Is this typical of most marital (or LTR) sex situations on this sub? I'm guessing so but curious to see if my suspicions are correct.
