　　Keeping the same posture for a long time in sexual life, always in the same environment, will make sexual life dull, and it is not easy to reach orgasm. Avoid entering the forbidden area during sexual life, so that you can easily have perfect sex.This means that best price for viagra 100mg It is the weather vane of the industry and can bring people great self-confidence. http://herbal-hall.com/Viagra-100mg(4-Pills).html

　　Many couples have been tricked into three misunderstandings about their sexual life!

　　1. Sexual life can only be in bed.

　　There is no fixed place for foreplay in sexual life, and it doesn’t necessarily happen only in bed. Husband and wife can casually tease, kiss and look at each other, or hint in language, which can attract each other’s sexual desire, and can transfer sex to the living room, study or sofa, private car, etc., which can give certain stimulation.

　　2, foreplay is too much trouble, go straight to the point.

　　Gentle foreplay is very important for women. When the penis is erect, it shows that men are ready to have sex, but it takes a certain time for women to get into a state of mind and physiology. During sexual life, a woman’s vagina should be kept in a lubricated state, so that the penis can enter smoothly and the pain in the vagina can be prevented. Before sexual life, you can properly appease, kiss and hug to stimulate sexual desire. In addition, you can’t fall asleep directly after sex. Try to take 30 minutes to warm or kiss, which can make the relationship between husband and wife more stable.

　　3. The longer the foreplay, the better.

　　Although foreplay is very important, we should also control the time. If the foreplay time is too long, it is possible that the penis will ejaculate directly as soon as it is inserted, which will affect the pleasure and beauty of sexual life. Foreplay can be controlled for about 10 minutes. When kissing or hugging, as long as you feel that there is something flowing out of the female vagina, you can insert it.

　　How to improve the quality of sexual life?

　　1. caress more

　　Gently caressing the sensitive areas of sexual partners can ignite and mobilize their sexual desire. In summer, husband and wife can sleep naked, and intimate skin contact can ignite the passion of sex. Women can try to kiss a man’s penis, which can make him feel warm and stimulate his sexual desire. More than two people, you might as well experience the feeling of cheating when you come back from a luxurious room, or try sex products to find new excitement and experience.

　　2. Change the time of sexual life

　　If having sex at a fixed time will make sex boring, you might as well change the schedule of sex, which will make both husband and wife fresh and exciting and experience different feelings. In addition, you should not eat too much before sex, otherwise it will affect your sexual desire.

　　Having a harmonious and regular sex life can not only make people feel happy in life, but also have many benefits for their health. However, after ten years of marriage, many people’s passion for sex life has been polished away. Sex life is like a stagnant pool. Without any waves, naturally, many benefits of sex life will not be realized. Sexual life is as dull as water, how to find the passion of the past? Let’s take a look at it next.The above conclusions show that viagra 100mg price To a great extent, it can bring new vitality to the market and make the industry develop well. http://herbal-hall.com/Viagra-100mg(4-Pills).html

　　Sexual life is as dull as water, how to find the passion of the past?

　　1. Leave the bedroom

　　If you have sex in a bedroom all the year round, it will give people a feeling that there is no change, and naturally it is easy to get tired of sex. If you want to get back the passion of the past, you must leave the status quo, at least from this bedroom now. If there are no children and old people at home, you can unlock other areas, such as living room, bathroom, kitchen and so on. If someone bothers you at home, the couple can sneak out on a date, and they can open a room in the hotel to rekindle their love.

　　2. Change the sex mode

　　Two people have lived together for a long time, and many people are too lazy to change. If they want to have sex, they should take a shower first, then foreplay, then use a few common postures, and finally end. This long-term sex pattern is very easy to kill people’s expectations for sex, which naturally makes sex life as passionate as doing tasks. To solve this problem, we must change the mode of sex. First of all, don’t have sex at a fixed time. If you have been having sex before going to bed at night, you can put it at noon or in the morning. Secondly, don’t always use sexy love, which was often used in the past. Nowadays, sexy love emerges one after another, and different postures have different experiences. You can learn from each other and then try. In short, don’t let yourself and your partner guess every step of your sexual life. If you can’t guess, you will naturally expect to be full.

　　3. Add some adventurous spirit to sex life.

　　Chinese people are always very introverted in their sexual life and are unwilling to express their true thoughts. This is the true feeling of most people in the face of sexual life. But if you don’t express your true thoughts and others can’t guess, naturally you won’t make your sex life particularly harmonious. If you want to rekindle your passion in sexual life, you must learn the spirit of adventure. You can meet two people to go to the field or have a car crash. It is completely possible to find a long-lost passion without affecting public order and good customs. Two people can also role-play and open the door to a new world. I believe everyone will stop.

　　4. Communicate more.

　　Communication is the best way to solve problems between husband and wife. Whether it is about sexual life or other problems about life, we should communicate and exchange more, so as to find the crux of the problem and know where to start to solve the problem. Some couples have some contradictions, and the existence of these contradictions will make them unable to devote themselves to sex life, and there is no way to get passionate, which naturally makes sex life dull as water. Two people can communicate more, solve conflicts as much as possible, at least to the point of reconciliation, so as not to be disturbed by external factors in sexual life.

　　After entering the marriage hall, the passion will be exhausted in the daily necessities, but this does not mean that it will always be like this. As long as two people work together and use these tips, I believe it is only a matter of time before they return to honeymoon passion.

　　In today’s fast pace of life, excessive life pressure, irregular diet and routine make many young men miserable. Long-term work is overloaded and mental stress is great, which unconsciously breaks the metabolic balance of human body and leads to energy overdraft.
