Premature ejaculation (PE) is a common sexual disorder in men, defined as ejaculation occurring before or shortly after penetration. There are several sex positions that may be beneficial for men with premature ejaculation. These include:

1. The Modified Missionary: This position allows the man to control the pace and depth of penetration, which can help to prolong ejaculation.
2. The Cowgirl: This position allows the man to control the pace and depth of penetration, which can help to prolong ejaculation.
3. The Reverse Cowgirl: This position allows the man to control the pace and depth of penetration, which can help to prolong ejaculation.
4. The Seated Position: This position allows the man to control the pace and depth of penetration, which can help to prolong ejaculation.
5. The Squeeze Technique: This position involves the man and his partner engaging in sexual activity, but when the man feels he is about to ejaculate, he stops and squeezes the head of his penis for about 30 seconds. This can help to delay ejaculation.
6. The Stop-Start Technique: This position involves the man and his partner engaging in sexual activity, but when the man feels he is about to ejaculate, he stops and waits for the sensation to subside before resuming. This can help to delay ejaculation.

It’s important to note that these positions may vary depending on the individual’s preference and what feels comfortable and pleasurable for them. Additionally, it’s important to have open communication with your partner and explore different positions to see what works best for both of you. It’s also important to mention that premature ejaculation can be caused by psychological and physical factors. If it’s a persistent problem it’s important to consult a healthcare professional to rule out any underlying medical issues and discuss different treatment options such as behavioral therapy, counseling, and medication.
