I take minor issue with #10. ["Did you come?"] I think it’s a bit romantic to presume that one’s partner will simply know whether the other has climaxed. Speaking purely in terms of my own (straight) relationship, I often ask whether or not my girlfriend came, not because I’m clueless but because I want to develop exactly the kind of keen sense your rule presumes.
Sometimes the answer is so obvious that the question would be pointless, but other times the line between orgasm and “almost” is very thin.
Granted, the question can be annoying, especially if it’s asked merely to place a period at the end of the sex sentence (Jesus, the sick ways that that metaphor could mix…), or to satisfy insecurity.
Communication being so essential to the Em & Lo sexual satisfaction program, however, I think we can be a bit more lenient with this particular question.
And yes, I did.
