A recent essay on Big Think says:
Birth control isn’t about my health unless by health you mean, my capacity to get it on, to have a happy, joyous sex life that involves an actual male partner. The point of birth control is to have sex that’s recreational and non-procreative. It’s to permit women to exercise their desires without the sword of Damocles of unwanted pregnancy hanging gloomily over their heads.
It seems to me that pro-sex rhetoric would have more traction if it gave some weight to the role of sex as an expression of love, which reinforces the bond of couples. Even independent of procreation, that’s a social purpose that the most pleasure-hating communitarian could at least grudgingly endorse.
