Hello, I'm Lee Young-jin, Director of Daegu Cornell Urology.
This time, I'll be discussing the fascinating topic: Is masturbation before sex a cure or a poison?

Is masturbation before sex a cure or a poison?
Curious, aren't you? In the same vein, there are many pros and cons about whether it's good or bad for athletes to have sex before a competition.

Some coaches absolutely advise against sex, saying it drains all your energy and can have a detrimental effect on the match that day. Other sports experts argue that it actually relieves tension, boosting hormone levels and ultimately improving performance. There are a sharp divide in opinions.

In reality, there are a surprising number of men who masturbate before sex.

"Before sex" here doesn't mean, for example, masturbating the day before, but rather masturbating at least one to two hours before sex.

Some men who masturbate before sex find it beneficial, while others find it detrimental.

For men who ejaculate too quickly, it can be a detriment.

This is because masturbation inevitably leads to ejaculation afterward, which can diminish sensation and make men feel more nervous. Don't you understand? After ejaculating, don't you feel tired and tense?

This tension is relieved, and because of this, the time it takes to ejaculate after masturbation can be significantly longer.
This can be a huge help for young men who ejaculate too quickly.
Secondly, young men in their 20s who are overly energetic and have strong erections can also benefit.

This is because being overly energetic can lead to more intense sex. Having sex after masturbation can reduce this pattern of intense sexual intercourse, making it less stressful for your partner. Therefore, for men who are truly energetic and want to be intense, masturbating before sex can definitely be beneficial.

However, there are many men for whom it can be toxic.
Men have a refractory period. In other words, whether through masturbation or sexual intercourse, after ejaculation, there is a period called the refractory period, during which erection and ejaculation become difficult.
This refractory period tends to lengthen with age.

Men in their 40s, 50s, and 60s who masturbate may find themselves unable to have sex even when they intend to.

In particular, problems associated with this refractory period, such as difficulty achieving a firm erection or controlling ejaculation, can arise. Therefore, men in their middle age and older should be aware that combining masturbation with sexual intercourse can be extremely harmful.
Secondly, if masturbation and sexual intercourse become a habit, it is very harmful.

Masturbation and sexual intercourse are similar, yet different concepts. If you're accustomed to masturbation—that is, you enjoy sexual activity in your own way, and you've become accustomed to stimulating the areas you find most sensitive—you'll likely develop a habit of masturbating and engaging in sexual activity. This can lead to some difficulties reaching orgasm or achieving sexual intercourse. Therefore, while it's sometimes beneficial to masturbate before intercourse due to the factors I mentioned earlier, you should be aware that habitually engaging in both masturbation and sexual activity can be detrimental.

There are quite a few men who masturbate and engage in sexual activity. Therefore, some men find it both beneficial and detrimental. If you watch my video and learn how to combine masturbation and sexual activity appropriately, you'll achieve the best sexual performance.

This has been Cornell's strength. Thank you.
