Five characteristics of men with strong "sexual ability"

1. Bright eyes and good gaze: The erection of the penis relies on blood perfusion, and if the liver is rich in blood, the erection of the penis is sufficient.

2. Black hair: male erection occurs under the action of androgens. People with strong androgen secretion will have a thick "black hair".  

3. White teeth and red lips: The heart is the engine of the human body and runs the blood of the whole body. People with a good heart can maintain sufficient blood supply during sex and will not "drop the chain" in the middle.

4. Buttocks and bee waist: men with strong buttocks have stronger fighting power and endurance. Strong buttocks are not only visual enjoyment, but also represent "actual ability."

5. The sturdy man: In terms of body shape, the sexual ability of the "rough man" may be slightly better. Men have well-developed muscles, strong body hair, and strong bones, which indeed reflect the majesty and masculinity of men, which are related to sexual ability to a certain extent.
