There are hundreds of varieties in large-scale adult product stores, but they can all be summarized into several categories:

1. Auxiliary and therapeutic equipment

Such as negative pressure or vacuum therapy equipment. It uses the principle of negative pressure or vacuum to passively congest and erect the penis to treat impotence. I personally think that one of its major disadvantages is that while the penis is congested and enlarged, it also blocks the return of blood to the penis, causing congestion in the penis.

During congestion, capillaries will expand and leak out due to lack of oxygen, resulting in non-specific inflammatory reactions. In the long run, this can easily lead to fibrosis of the corpus cavernosum and irreversible pathological impotence. Please consider carefully before use.

2. "Aphrodisiac" category

The only drug in the world that is considered by the medical community to have real "aphrodisiac" effects is extracted from an insect, which Hong Kong people call "Spanish fly." Its principle of action is that after taking it, it is quickly excreted through the urethra and stimulates the urethral mucosa. The stimulating signal is simultaneously transmitted to the sexual organs, triggering sexual desire.

And I discovered that the "aphrodisiacs" sold in some sex shops in mainland China are hormones or neurostimulants! Abuse of these drugs can be harmful to your health, so please be careful. I personally do not agree with the use of drugs to "aphrodisiac". Sex is a purely natural instinct. If you rely on drugs to maintain "sexual interest", it is already a poor choice and has no meaning.

3. Strengthen sexual stimulation

For example, the glans coronal ring (an elastic ring with protruding stimulators, fixed in the coronal groove under the glans), and the penis jacket (mostly made of silicone, which can 'enlarge and lengthen' the penis, often with protruding stimulators) , condoms with protruding stimulators, etc. Their function is to increase and strengthen the stimulation of the vagina, thereby making it easier for women to reach orgasm.

4. Local anesthetic

Represented by various "magic oils", its working principle is to act as a local mucosal anesthesia after being applied to the glans to reduce the sensitivity of the external genitalia, thereby increasing the stimulation intensity (threshold) for ejaculation and prolonging the time of sexual intercourse.

This is a good treatment method for patients with premature ejaculation caused by excessive sensitivity of the penis skin and glans mucosa. But if premature ejaculation is caused by central nervous system disorders and the brain's threshold for sexual excitement tolerance is too low, such drugs will have no effect.

5. Lubricants

This type of product is suitable for women who lack sexual arousal or are post-menopausal. It lubricates the vagina and reduces discomfort and even pain during sexual intercourse. It is also suitable for women who have little sexual experience and are too nervous to be fully sexually excited. It allows women to easily get used to and adapt to the insertion of the penis.

6. Masturbation products

There are ones for men and women. They are good substitutes for men and women who lack sexual partners. We have already said that sexual impulse is a kind of energy. Rather than painfully suppressing it, it is better to allow it to have a suitable release channel.

7, other

Such as products that increase sexual interest, some special sexual products, etc.
