I ask because my wife and I have a very climax-centric sex life. 99% of the time we both cum, and sometimes several times. On a rare off one of us will just want to please the other one, and not finish. And yes, sometimes the party that did finish is disappointed because we both love to make the other cum.
Is there a chance your wife is just disappointed because she loves to know you finished?
Sounds like us again Jaquen (minus the "several times") ~ that must be nice

I'll never forget the 1st time my husband DIDN'T get his... it was 4 yrs ago (after being married almost 20 yrs)... I was wearing him out with needing my FIX all the time.... I got mine ...and he told me he didn't think he could get his...that he'd wait till the next day... ....suddenly these emotions started washing over me....this feeling of sadness....It bothered me.... it's like I want him to GET HIS
[email protected]#$%^ Let's just say, it was a new experience for me, and it kinda took me by surprise.
I had to remind myself I was pushing his limits, and be happy he still wanted to please me. For a time I questioned if I was being a "burden" ...but he assured me I wasn't. ... then this became easier... and about once or twice a month...this would happen, and it was OK... I knew he was still happy to be there , my pleasure = his pleasure.
And he is the same darn way ! He feels sadness if I can't get mine, he even got glassy eyed once when I told him to take me sideways - cause I didn't think I could go again (just did it the night before) -here he was worried I was slowing down- even asked me that ....that proved to me right there -how deeply he felt about pleasing me.. that he almost gets MORE pleasure out of pleasing me. He passed that morning for his own.
Some people (at least we are) are pretty sensitive to these things - but in your wife's case,
sounds it is more related to HAVING A BABY...
I can surely understand this a TON.. we had over 6 + years of trying to conceive... I wanted more children badly... and (hate to say it)...I was very one tract minded, I really didn't even think of his pleasure, all I wanted was his
... this hurt him because at that time, I didn't care about my own pleasure either... if any position or MY NOT orgasming (suggested to get a girl)- that is all I cared about.
I can't say he ever failed to perform once though back then. If so, I can easily see me getting upset and wanting to do it again like hours later - to make up for our scheduled attempt.
When a woman wants a baby and she thinks she has the right timing down, that is kinda devastating to her. Are you having trouble conceiving? They say unprotected regular sex - over one year, if no conception -could warrant some testing..
So is this more related to her wanting a baby (which I am suspecting -even if she doesn't say that)....or she just cares deeply about your pleasure ?
