I said " ... no room for nuance ... " (above). What I'm trying to get at here is that while sexual activity will always be emotionally intense activity for healthy people, that need not mean that everyone who "has sex" has got to immediatly go out and find a preacher and get themselves married and have children and pick out drapes and dishes.
There are MANY ways to have emotionally intense connections with people. Sexual activity will always involve emotional intensity -- sans pathology. One need not get married to be emotionally involved with others. But that leaves a lot of wiggle room, doesn't it? Must we pretend that sex is akin to bowling together? It obviously isn't. I HOPE!
