In the longer-term, a successful sex life involves continuing to enjoy each other's company in a broader sense than just sex.
It involves demonstrating affection by reacting sensitively to each other's needs. If a man wants his partner to make effort in sex, then he will need to invest in the emotional intimacy she needs to feel amenable to sex.
"Men, remember, feel good as a result of having sex. Women want to feel good before having sex." (p260 How Men can get more Sex and Women can get more Love 1994)
Sex tips for men
Try to show that you appreciate what your partner has offered in the past and be ready to give her some space when things are not going so swimmingly for her later on.
Here are some suggestions:
"Just as a man forgets feelings, a woman forgets her sensual desires and longings. The practicalities of day-to-day survival and living take precedence over their deeper and more sensual desires." (p32 Mars & Venus in the Bedroom 1995)
"This does not mean that every time I do the dishes, she is supposed to have sex with me. That would not be romance. That would be a business deal." (p201 Mars & Venus in the Bedroom 1995)
