Ah, the possibility of pregnancy with all that goes with that....
Trying to get pregnant made my wife very demanding with PIV sex. She calculated dates/temperatures etc carefully, and then took complete control. It became quite perfunctory for me - unlocked, service her, locked again. More like work, than sex. She almost never orgasms unless I am inside her, so I always had to wait for her to orgasm first.
But this is exactly the way I want it.
Now she is very pregnant, and she finds intercourse uncomfortable, especially with getting accustomed to my PA piercing. So we are very unlikely to have PIV sex for some time.
Fortunately for me, she is still interested in playing in other ways, but ejaculations are few and far between (two since she fell pregnant last September).
Sigh...
