Some dangerous preludes to sexual behavior should be noted. Otherwise, you won't get the pleasure you want. As is well known, when couples have sex, in order to increase interest, the pleasure becomes more intense, but some foreplay cannot be done. Doing too much actually doesn't help with sex. Or it's best not to do it.
Dangerous Prelude 1: Movie Risk Index: ★ If effective, one of the reasons why erotic movies appear is that the levels of sex hormones in the body increase by a few percentage points before sex. However, the latest research shows that increasingly fragrant visual stimuli excite the human nervous system, and under such high stimuli, the brain is often in a state of hypoxia during sex. Temporary brain hypoxia can bring dreamlike pleasure to some people, but over time, if the brain hypoxia exceeds the physiological limit, people will feel dizzy, and if the brain hypoxia exceeds the physiological limit, people will feel dizzy, ovarian dysfunction will affect normal ovulation, and men will have difficulty erecting or persist for a shorter period of time. Alcohol induced sexual activity increases testicular binding globulin in males, damages the testes, and weakens the production of testosterone. In addition, 70% of sperm after drinking may develop poorly. If pregnant in this situation, 26% of fetuses will experience health problems, especially intellectual disabilities. Support: Whether you choose champagne, strong Baijiu, popular beer, or wine with health signs, you will "abstain" within 2 hours after drinking.
Hazard Prelude 2: Hot Water Bath Hazard Index: ★★★★★★ Before having sex, I like to clean and take a shower first. Of course, there is no thickness, but many people use a couple's bath for dozens of minutes as a prelude to sex. In fact, a hot water bath lasting more than 5 minutes will consume a lot of physical energy, and sex requires sufficient physical reserves. In this situation, having sex often shortens the time. At the same time, the human body gradually relaxes under the action of hot water, and the whole body enters a resting state. It is difficult for various organs to quickly excite. Intense sexual activity can cause rapid congestion and damage to organs, and rapid traction movements can easily damage muscle fibers. Most importantly, prolonged hot baths can reduce the sensitivity of the human body, especially female organs, making it difficult to reach orgasm. Support: If you want to do body cleaning before sex, limit your time to less than 5 minutes, and enjoy a romantic double bath, please transfer the lingering time to after sex.
