Not necessarily, because there’s more to a healthy relationship than sexual intercourse. It's all communicating one's feelings. Being romantic solely just to get sex will be seen as manipulative. Hinting at your desires will most likely push her further away, and doing nothing about it will make you resentful, making the relationship ready to fail.
When communicating your feelings, it's best to have the conservation with your wife in a neutral place where sex isn’t an option. A coffee shop or a long walk in a public place are good ideas. Talk to her about what intimacy means to you, but also plan out in advance what you hope to say.
It's best to have the attitude that you’ll work through the issues together. When you go out let her know that you would like to talk about what sex means to you and the benefits that a fulfilling sex life would bring the both of you.
Not, necessarily! There are some people who do fall in love because they have great sex together. There are already some stories of those who started out to have one-night-stands. The more that they get together, the more that they get to know each other. They may start talking and eventually fall in love.
Husbands and wives would need to have sex up to a certain point in their lives. The time will come when they will be there for each other for the companionship and not for the sex anymore. There are also other things that you may do for your wife so that she will love you more. Treating her right will always be appreciated.
