How does a male brother get an erection? Does it depend on the woman to arouse his sexual desire? Or does he find a way to arouse his own sexual desire? What is the problem if his erection lasts only a short time? ?

The question must be from a girl. When a man with normal physiological functions touches the skin of the woman he likes, he will naturally have sexual impulses. This is his instinct and a natural physiological condition. process. It's not what you imagine. You have to choose very deliberately and hard every time to have sexual desire. Besides, men are also susceptible to visual stimulation. Sometimes they don’t need a specific person to be around. Seeing stimulating pictures, seeing photos of their lover, fantasizing about a certain woman, or hearing certain sounds may also produce sexual desire.

When he has sexual desire, the brain will give an instruction to his "brother" through endocrine, blood, and nerves. After receiving the instruction, the structure of the younger brother will change, resulting in an erection.

So, sexual desire is not only provoked by the woman, nor can any woman be provoked. Personal emotions, preferences, and mental status have many factors to do with it. For example, if a man sees a woman he hates very much, it may be difficult for him to have sexual desire no matter how much he is teased. When he is very tired and exhausted, it is probably difficult to have sexual desire even if he hugs his lover. Of course, flirting can also be a way to turn him on.

The last question is that the duration of an erection is also closely related to personal emotional and mental conditions. The end of an erection represents the end of the sexual impulse, either because the sexual stimulus is removed or because the sexual impulse has been released ( After having sex, after masturbation), etc.
