sex tools

These are devices that help men and women overcome their sexual difficulties and achieve sexual responses like normal people. However, they are not a panacea; they can only help induce or enhance the arousal of the sexual organs. The use of these devices has a long history and is widely applied in various cultures. For example, various types are described in the novel *Jin Ping Mei*, and similar descriptions can be found in ancient Greek and Roman paintings. Currently, commonly used clinical devices include:

1. Male negative pressure suction devices.

These devices come in various forms, becoming increasingly sophisticated and advanced, but they all essentially work by using negative pressure to passively induce an erection or swelling of the penis, then fixing it to the base of the penis with a tourniquet to maintain the erection. However, this erection is often not very full, so the penis is mostly in a suspended state rather than firmly upright, which may be unsatisfactory for the patient. The most common problems are that patients feel it is unnatural or difficult to use, such as the sleeve not fitting tightly to the skin when applying negative pressure, difficulty in removing the tourniquet, delayed or absent ejaculation, and low skin temperature. A small number of patients may experience subcutaneous bleeding, ecchymosis, and edema. Therefore, tourniquet use should not exceed 30 minutes, and the negative pressure should not be too low, otherwise it will affect the adequate blood supply to the tissues and cause some unnecessary side effects.

Negative pressure suction technology has existed for over 70 years, but its widespread application is only a recent phenomenon, dating back to the last decade or so. In recent years, many domestic manufacturers have emerged, resulting in shoddy and unethical products. This has led to two problems: firstly, it has damaged the reputation of negative pressure suction technology, and secondly, it has caused inconvenience to patients. For example, some manufacturers only care about making money, and they don't even print instructions or make them too simple to understand, resulting in patients not knowing how to use them; others heavily advertise "marital bliss," leading healthy couples to buy them, which is completely unnecessary. Furthermore, the production of tourniquets lacks scientific consideration, often resulting in tourniquets

that are too small, making the pain of removing the tourniquet far outweigh the brief pleasure of intercourse. Negative pressure suction devices are available in pharmacies. Foreign negative pressure suction devices are well-made, rationally designed, and easy to use, but they are expensive, costing at least 1500 yuan, which is prohibitive for many.

2. Penile Health

Ring: This ring is a circular air bladder. When inflated, it creates a "gripping" effect at the base of the penis, reducing venous blood return and ensuring full blood flow to the corpora cavernosa, promoting continued erection. Combined with massage, it can enhance the strength and duration of erection, improving sexual function. It is suitable for weak erections and also has a significant effect on overcoming premature ejaculation.

3. Artificial Vagina:

This can be helpful for patients with erectile dysfunction. Because it contains a vibrator or peristaltic device, it provides a certain massage and stimulation to the penis, aiding in its functional recovery. Modern artificial vaginas are made of high-grade plastic and come in hand-held or integrated into the entire plastic female body. While expensive, those made abroad are well-made and feature-rich, making them a viable option.

4. Vibrator:

Powered by batteries or AC, it typically uses a small motor to drive a cam device, producing oscillations at a frequency of 80 times per second or an adjustable frequency. This high-frequency stimulation easily arouses increasing sexual excitement and helps patients with ejaculatory dysfunction quickly overcome the orgasm threshold, thus overcoming orgasmic obstacles. Vibrators come in male and female versions. Male versions are generally designed in the shape of a semen collection device, while female versions are designed in the shape of a penis. There are also universal versions. However, we must remember that instruments are instruments after all; they cannot replace human emotional investment and real feelings. Therefore, we cannot rely entirely on tools; they can only play a certain auxiliary role.
