This may be an unusual complaint (or maybe not so much complaint as an observation) but sometimes when I'm really into it I feel like I'd like to be going down on my wife for much longer than she likes (or longer then she can take). After 10 ten minutes or so she usually cums 2 or 3 times and says she's too sensitive and wants us to move on to doing something else. Meanwhile, there are times I'd be into doing it for an hour or more. I sometimes try taking it very slow and gentle, but that doesn't really change things. My impression is that most women wanted their guys to do it longer than their guy wanted to - maybe we just have it backwards? Any other guys have this issue?
