Sexual therapy
In some cases, sexual therapy may involve simple steps such as masturbating an hour or two before intercourse so that you're able to delay ejaculation during sex. It is recommended avoiding intercourse for a period of time and focusing on other types of sexual play so that pressure is removed from your sexual encounters. Go for a Squeeze technique. This method works as follows:

• Step 1. Begin sexual activity as usual, including stimulation of the penis, until you feel almost ready to ejaculate.
• Step 2. Have your partner squeeze the end of your penis, at the point where the head (glans) joins the shaft, and maintain the squeeze for several seconds, until the urge to ejaculate passes.
• Step 3. After the squeeze is released, wait for about half a minute, then go back to foreplay. You may notice that squeezing the penis causes it to become less erect, but when sexual stimulation is resumed, it soon regains full erection.
• Step 4. If you again feel you're about to ejaculate, have your partner repeat the squeeze process.

By repeating this as many times as necessary, you can reach the point of entering your partner without ejaculating. After a few practice sessions, the feeling of knowing how to delay ejaculation may become a habit that no longer requires the squeeze technique.
