Perel: Couples grow apart by experiencing differences as threats

Perel: Relational security requires balancing safe anchoring with independent freedom

Insight
Nagoski: Sexual well-being is measured by pleasure, not performance metrics
“Pleasure is the measure of sexual well-being. It's not about how often you do it, who you do it with, what room you do it in, what positions, how many orgasms you have. It's whether or not you like it.”

Nagoski: Post-sex cuddling predicts relationship satisfaction better than sex frequency

Insight
Nagoski: Couples sustaining long-term sexual connection share friendship and prioritization

Iacenza: Sexual encounters do not always need to be mutually reciprocal
“You don't have to always have, be, have reciprocal sex every time you do it. That's also a burden. Many couples don't have sex because one of the partners may not want To let's say, be up for an orgasm, or even be able to experience arousal that easily, so the…”

Iacenza: Sexual initiation patterns are socially constructed rather than biological
