People need to hear this more. Will Duquette (are you reading Will Duquette? You should be!) says
It is true that the first stages of Eros are like shooting the rapids on a river: exciting and scary, and great fun, especially if you’re an adrenalin junky. But mature Eros is that like that same river, downstream: wide and deep, flowing strongly, deeply peaceful but in no way static or stagnant. Oh, yes: and sometimes there’s sex involved, and it gets better over time, especially when you get over the need for thrills. No, really. The sex is supposed to be about the two of you, not about the sex, and it’s difficult to get there if you’re focussed on the thrills.
Read the rest (it’s short!). Lots to ponder here.
