why did girls like sex?

Women want to be praised
For a couple that has been together for long, sometimes it is natural that women may feel that their partner may find them less alluring. Because of this some women undress only under the cover of darkness. Caring men can sense such anxieties. There is no need to lie and say she's gorgeous if she isn't, nor is there a need to say that she is not attractive anymore. One can always appreciate and praise what you do find attractive.
For a woman sex isn't separate from rest of her life
On the other hand, men tend to compartmentalize, feeling that stressful aspects of life can be parked mentally and separated from sexual activity. Women need good feelings and experiences during the day to have satisfying sex. How her lover treats her out of bed, greatly influences her response in bed. Inattentiveness, harsh language, rude tones, hurtful words, and criticism can make it difficult for a woman to get involved, feel enthusiastic and be passionate during sex.
An orgasm is not a necessity
Many men feel that a good lover is one who can bring his woman to climactic sexual culmination. It is great to have such moments, but aren't always essential. Many women feel pressure from partners and even from themselves to reach an orgasm. Sometimes instead of having orgasms, women prefer to engage in just foreplay.
Sex need not be a serious act
Playfulness is a great quality. Many men are far too serious about sex. They forget to laugh, be romantically mischievous, have fun. Playfulness and light-heartedness can make intimate moments enjoyable and relaxing. This takes performance pressure off from both partners.
Women cherish non-sexual touching and tenderness
Women love romance, cuddling, hand-holding and kissing. But many women complain that their men never do this except during foreplay. A woman should make her man realise the joy of touching. As you give him a relaxing massage and stroke his face and hair tenderly, he starts experiencing the joy of this kind of non-sexual touching. Tell your man what makes you feel loved and wanted.

Warm attention after sex is important
A woman's need for tender moments goes beyond the actual lovemaking. Some women complain that men fall asleep immediately after the act. It is true that when a man is having sex, his endorphin level is very high. Almost immediately after ejaculation, he goes through a refractory phase where he loses his erection and all his systems gear down. In females this phase happens gradually. However, if you don't like him falling asleep immediately, tell him without putting him down. Alternatively, let him sleep in your arms for a few minutes and gently wake him up afterwards.
Men talk and think a lot about sex while women desire it more often. We explore the reasons...
'Men think, while women desire.' Gone are the days when ‘demanding sex’ was considered exclusively a man's forte. Today women demand sex greater than men. And they have no qualms about getting vocal about it. “I read these funny E-mail forwards that stress on men begging for sex and women denying it. It sounds so funny to me. It’s totally the opposite in my case. While men can have a good laugh over it believing that this notion exists, I literally have to seduce my husband to get him hooked on to the act,” quips production assistant Mughal Mishra. And she is not alone. Many girls/women had a similar story.

It’s physically pleasurable
Amongst all the other reasons to remain glued to sex, this is the most prominent one. Good sex satisfies your physical urge, which is very normal for anyone to experience. Psychologist Seem Nanina opines, “Sex is the most basic need of any person. And I am increasingly getting cases where women are complaining that men are unable to satisfy their physical needs.”
Creates positive feelings about oneself
Ideally, great sex means you are enjoying the sexual act and participating equally. It makes you feel good about yourself, thus adding to your self esteem. Shares housewife Neel am Nehru, “When my husband comes back from a whole day at work and we have our sack session, it increases my self esteem. The very feeling that I am able to satisfy him is a great pleasure. And since I never want to go out of shape to look unappealing to my husband (and other men), it even acts as a motivation to work out and feel desirable.” Wondering why?

"Sex has healing powers. It generates positive emotions and makes one feel more confident. When a woman sees her man passionate in the act, admiring her body and moves, it infuses a lot of good feelings within her," opines psychologist Susana Bajaj.

Brings them closer to their man
Physical intimacy releases hormone Oxytocin, which is also known as the love hormone. Agrees relationship expert Vandana Mitra, “I have always maintained that couples should never take sex casually. It’s a very important ingredient for any relationship to sustain. It helps couples to nurture the relationship and strengthen the bond.” So whoever said having more sex with your partner means lesser cases of infidelity, made sense.

Content developer Prachi Sinha states, “I feel a major connect with my boyfriend after we make love. I just feel like being close to him. My faith in him and our relationship grows stronger.” Prachi’s boyfriend agrees, “When she told me about the 7 days a week sex, I initially could not stop laughing. I mean, this is not the only thing we have to do. But honestly it has got us closer. I just can’t take my eyes off her even when we are moving in a crowd.”
