During mutual masturbation or 69 I can't go on pleasing my partner after a while because I feel too good and can't do anything other than moving my hips and a bit of kissing. It would be okay if it was just seconds before the orgasm, but it is way more than that.
I want to keep pleasing my partner during that time but I can't reciprocate at that moment. I try to concentrate and go back to him but I become useless again after a few seconds.
He says it's okay, but I would still like to be able to do it at least every so often.
Also, I have to mention that I do take care of him after that, and that this doesn't happen during penetrative sex because I don't need to coordinate many things then.
