Sexual expression, sexual release, and male contraception
**III. Sexual Expression**
Sexual expression refers to the ways in which male and female sexual behaviors (including courtship, sexual intercourse, etc.) are expressed. Based on data and observations, it can generally be divided into two categories: heterosexual sexual expression and homosexual sexual expression.
Heterosexual sexual expression refers to sexual expression between married couples or men and women in love. The ways in which this expression takes place are often diverse and not limited to any particular form, posture, or position. As long as it is within the bounds of physical health and social, legal, and moral boundaries, any words or actions that achieve sexual arousal, attraction, foreplay, or afterplay are reasonable and permissible, aiming to achieve and enhance the effects of sexual expression in love and sex.
Homosexual expression, whether between men or women, is characterized by one partner being active and the other passive, or by the two taking turns and exchanging sexual roles. Among men in homosexual relationships, older partners are more likely to be active, while the passive partner is often a teenager or younger (often with a "pretty boy" physique). Their sexual expressions often involve anal or leg sex, and other expressions such as touching, kissing, and hugging can be similar to those between heterosexuals. Among women in homosexual relationships, older or physically stronger partners often dress as men or exhibit masculine-like active sexual expressions; younger or more delicate partners are more passive, and their sexual expressions often involve mutual masturbation, the use of vibrators, or the insertion of double-headed penises into both vaginas. Other expressions such as touching, kissing, oral sex, and close contact are also frequently used. In reality, both of these types of homosexuality represent forms of sexual perversion.
In addition, emotional expression during sexual behavior often affects the effectiveness of sexual expression. For example, joy is often expressed as sexual pleasure, tenderness, and shyness, while anger is often expressed as jealousy, resentment, and coldness, and fear is often expressed in premarital or extramarital sexual behavior.
**IV. Sexual Release**
In general, normal sexual desire involves two complementary processes: the accumulation of desire and the release of desire, which wax and wane. Release is the final outlet for sexual desire. Sexual desire is a human instinct that needs constant satisfaction to release its energy. Unmarried young men and women primarily release their sexual desire through masturbation and other forms of self-gratification; married couples mostly use intercourse to release their desire, but some also use masturbation as a supplement. Sexual release can produce sexual pleasure or satisfaction, and after release, it reinforces the accumulation of sexual desire, thus creating a cyclical process. However, if one releases sexually without restraint in an attempt to obtain frequent and abundant sexual satisfaction, it often leads to decreased libido, lack of sexual pleasure, and ultimately, sexual dysfunction and other painful conditions. Therefore, appropriate restraint in sexual release, rather than indulgence, is a very important health measure that aligns with the principles of sexual health. Of course, advocating sexual repression and abstinence also violates sexual instincts. Therefore, both release and repression must be moderate to maintain one's health and adapt to modern social norms.
When conditions and circumstances are unsuitable for fulfilling sexual desires, some people can substitute them with a positive desire for work and knowledge, transforming sexual desire into a new driving force for another type of work and desire. Generally speaking, individuals with sound personalities are often adept at managing their sexual desires, turning them into a driving force and source of new creations, thereby achieving new psychological satisfaction. This is what is commonly referred to as the sublimation of sexual desire.
**Section 3** **Male Contraception**
**I. Condoms (Safety Condoms)**
This is a contraceptive method where a thin, resilient, transparent round sheath is placed over the penis. It does not interfere with sexual intercourse but prevents sperm from entering the vagina. The condom is a very thin, transparent round sheath made of latex rubber. Its primary function is to prevent pregnancy; it works as a barrier contraceptive. When the man wears the condom during intercourse, semen is only ejaculated inside the condom and cannot enter the woman's vagina. This blocks the opportunity for sperm and egg to meet, preventing fertilization and thus achieving contraception.
One minor drawback of using a condom is that during intercourse, both partners have to pause for a while so the man can put the condom on, which reduces sexual pleasure. This problem can be solved if the condom can be used as part of foreplay, with the woman putting it on for her.
A condom is a cylindrical, thin film sheath made of high-quality natural latex, 19cm in length. At the distal end is a 3cm long reservoir called the seminal vesicle, which stores semen during intercourse. The proximal opening (the opening) has a slightly elastic rubber band that securely holds the penis. Condoms are available in four sizes based on the diameter of the opening: large (35mm), medium (33mm), small (31mm), and extra small (29mm).
Condoms are a simple and effective contraceptive method, but improper use can easily lead to failure. The correct way to use a condom is:
(1) First, select a condom of the appropriate size. Then, use the air blowing method to check the condom for any damage. If any leakage is found, it should not be used. After checking the condom, roll it up as before.
(2) Before putting on a condom, pinch the small reservoir at the tip to squeeze out the air. Then place it on the head of the erect penis and push the folded part of the condom towards the base of the penis while putting it on. After putting it on, the small reservoir at the tip of the condom should hang in front of the penis. Do not put the head of the penis into the reservoir, as this will not only make it easy to burst, but also affect sexual pleasure.
(3) Applying some contraceptive cream to the glans penis and the outside of the condom can improve the contraceptive effect and lubricate the vagina to reduce discomfort. However, do not apply too much to the glans penis, otherwise the condom may fall off.
(4) After ejaculation, before the penis softens, hold the opening of the condom with your hand and pull the penis and condom out of the vagina together to prevent the condom from falling off in the vagina after the penis softens or semen from leaking into the vagina from the opening of the condom, which would cause contraceptive failure.
(5) After intercourse, the condom should be checked for breakage. If it is broken, remedial measures should be taken in time.
There are many benefits to using condoms: First, they are convenient to use and carry. Modern condoms are coated with lubricant, and some are wrapped in aluminum foil for long-lasting protection. To use, simply place it on the glans penis and gently pull it on. Second, there are no adverse side effects because they work by physically preventing sperm from entering the uterus, unrelated to any hormonal or chemical reactions. Some people believe that using a condom will affect the pleasure of intercourse, but this is untrue. In fact, many people don't even feel the condom's presence when using it, and condoms are inexpensive and readily available, so they are bound to become increasingly common.
