The sex relation is not a personal relation. It can be irresistibly desired and rapturously consummated between persons who could not endure one another for a day in any other relation.
I have been to this point unwilling to sign on to same-sex marriage primarily because of my understandings of the traditional definitions of marriage. But I also think you're right that attitudes evolve, including mine.
In masturbation there is nothing but loss. There is no reciprocity. There is merely the spending away of a certain force, and no return. The body remains, in a sense, a corpse, after the act of self-abuse. There is no change, only deadening. There is what we call dead loss. And this is not the case in any act of sexual intercourse between two people. Two people may destroy one another in sex. But they cannot just produce the null effect of masturbation.
Marriage...is the union of two people of different sexes with a view to the mutual possession of each other's sexual attributes for the duration of their lives.
I am not prone to weeping as our sex commonly are; the want of which vain dew perchance shall dry your pities;

Loss of virtue in a female is irretrievable; that one false step involves her in endless ruin; that her reputation is no less brittle than it is beautiful; and that she cannot be too much guarded in her behaviour towards the undeserving of the other sex.
There is a brief time for sex, and a long time when sex is out of place. But when it is out of place as an activity there still should be the large and quiet space in the consciousness where it lives quiescent. Old people can have a lovely quiescent sort of sex, like apples, leaving the young quite free for their sort.
It is only the man whose intellect is clouded by his sexual impulse that could give the name of the fair sex to that undersized, narrow-shouldered, broad-hipped, and short-legged race.
The sex illusion is not a fixed quantity: not what mathematicians call a constant. It varies from zero in my wife's case to madness in that of our stepsister.
It is true from early habit, one must make love mechanically as one swims; I was once very fond of both, but now as I never swim unless I tumble into the water, I don't make love till almost obliged.
