Welcome to healthcaremagic, Premature ejaculation is commonly seen in men under 40 years of age. There are many different methods which can be used to delay ejaculation. It will take some time to learn these techniques, so your friend must have patience and practice them. 1. Wearing a condom - it reduces stimulation for most men, which should prolong the time before ejaculation. There are special condoms also available such as delayed pleasure condoms etc which are helpful. 2. Masturbate to orgasm an hour or two before intercourse, this can help delay ejaculation during sex. 3. Squeeze Method - Begin sexual activity as usual, including stimulation of the penis, until almost ready to ejaculate. Squeeze the end of penis, at the point where the head (glans) joins the shaft, and maintain the squeeze for several seconds, until the urge to ejaculate passes. After the squeeze is released, wait for about 30 seconds, then go back to foreplay. Squeezing the penis causes it to become less erect, but when sexual stimulation is resumed, it soon regains full erection. Repeat the method few times. 4. Stop-and-start method - Have intercourse as usual until he feels coming uncomfortably close to orgasm. Immediately and abruptly cease all stimulation for 30 seconds, then start again. Repeat this pattern until he is ready to ejaculate. 5. Avoid penetration for the first 15 minutes of lovemaking. Focus on other sexual play initially. 6. Reduce anxiety - For many men anxiety and pressure to perform is a major contributor to premature ejaculation. Extend your support to him. Regular exercise and yoga are also helpful. Hope that answers your question. Regards, Dr.Imaad.
