My own thoughts on fornication and adultery in specific are slow in coming right now, but Steven Greydanus has an excellent piece up at Jimmy Akin’s blog dealing with sex, its multiple purposes, and how those multiple purposes can go right or wrong depending on intent. I especially like

Whatever aspect of sex is a couple’s motivation tonight, either they take the occasion to accept the mystery of sex in its fullness, insofar as it is available to them, or they seek to reject and exclude some or another aspect, to the detriment of the act itself and their own being.
It is my hopes with my next post to speak directly to what those detriments that SGD mentions are, especially in terms of trust, deceit, relational bonds, maturity, and so on.
