Here's how you explain it to your kids: "Mummy and Daddy love one another very much, and so do lots of other people. Men love women, some men love other men, some women love other women. And when they love each other enough, they commit to being with that person for the rest of their lives and get married."

I'm not totally sure how a conversation like that means - as some same-sex marriage opponents seem to think - that one has to start describing the intricacies of sex, anal or otherwise.

I do think it's utterly disappointing that the primary reason people seem to think that denying same-sex partners from getting married is because they are too much of a pussy to explain to their kids that gay people exist and can love one another.
