Generosity for the win: Focusing on what she craves in the sack also increases your arousal, says research in the journal Social Psychological and Personality Science.
Researchers studied “sexual communal strength”—the willingness to meet a partner’s sexual needs—in long-term couples. Both parties filled out daily sex surveys for 3 weeks. Four months later, generous lovers reported higher levels of daily arousal AND more desire for their partner than the less-generous couples.
