Protecting erotic time is the unromantic decision to guard the hours and energy a sexual relationship needs, instead of leaving intimacy to whatever scraps survive work, chores, and exhaustion.
It treats time, attention, and unspent energy as finite resources that sex has to compete for — and decides to let it win sometimes. The insight is plain: sex never sends invoices or wakes you at 3 a.m., so left to compete on those terms it loses by default, quietly, until a couple looks up to find it has been months. This sits one level above honoring tonight's actual energy (#159): it works at the level of the calendar, deciding in advance that there will be energy to honor. It is also not date night or courtship (#168) — you can have a lovely weekly dinner that never once makes room for sex.

Much desire emerges after a person enters a low-stress, affectionate context rather than arriving beforehand 35 — so protecting that context is the mechanism by which desire becomes available, not optional extra credit. The trap is sharpest for new parents, who lose the whole infrastructure of spontaneity at once 8.
How to cultivate it
How to cultivate it. Name the leftovers problem together without blame, then guard conditions — an unhurried, low-stress window placed where energy actually exists — while letting what happens inside it stay genuinely optional 23.
The honest caveat
The honest caveat. The directly relevant evidence is two studies from a single research group on largely North American samples, and it argues against the spontaneity myth rather than proving that any particular schedule revives a flagging sex life 12.
