If you had been telling your wife to come with you when the time has been right all along in your marriage, you wouldn't have to be worried about your wife needing lube because her conditioned body would be juicy enough for her inevitable response to your respectful dignified reasonable request, in the form of a command, would be for her to come with you… Men don't tell women to cum any more because women start laughing at the ridiculousness of it all, when men did not wait to say the word until the time came when it was possible. It used to be rather common knowledge that if you tell a woman to cum with you when you are cumming, she will get a vicarious thrill and naturally begin to coordinate and synchronize her cllmaxs with yours. If she loves you enough to let this happen.
