My wife and I are both mid-40s. Throughout our relationship I've been lucky enough to be able to give her orgasms through PIV most times, and I used to be able to time things so that I would orgasm soon after she'd had two or three.
As I get older, I'm a bit slower. These days after 10 or 15 minutes she's had her orgasms but sometimes (maybe one-third of occasions) I'm not close yet. I can tell that she really loses interest. Sometimes she'll try to keep going for a bit, but it feels weird if she's just mainly waiting and hoping I'll finish. I had hoped she might feel like helping me finish via HJ or BJ, and occasionally she tries for a minute or two but again it seems like she's trying to rush through it (and then pauses and says "are you close?") and hopes to be done, like it's a chore. I've been saying things like "only carry on if you really want to" and often she'll just stop.
I would never want her to do something she didn't want to, but my question is: is it common for women to kind of "switch off" after they've orgasmed? I know it's a stereotype for men, and indeed physically I am "one and done" in terms of my own body, but mentally I'm still keen to do other things for her if I come before she does (which is very rare.) Is there anything I can do to make it more appealing for her to keep going in some way? I've talked with her a bit but she's not very comfortable talking about these things.
