Although it is not at all uncommon for such lovers, who have fully learned this art, to go to sleep thus, in each other's arms, their sex organs united; and, in this position, have the organs detumesce, the penis grow limp and slip out of the vagina of its own accord, while the vagina also grows small and the clitoris subsides.
On the other hand, if the wife comes to the orgasm first, her vulva and vagina detumesce but little and that very slowly, so that it is perfectly possible for the husband to continue his action, and come to the climax, even if his partner has already "spent."
Of course, as has already been explained, the husband always has the advantage, that he can be brought to the orgasm by the insertion of the penis into the vagina, _after_ his wife has spent, if she arrives first, since her organs detumesce slowly, and their distended condition permits such action on his part, for some time after she has passed the climax.
