Isaac these are some recommendations to help with the premature ejaculation.
1. Masturbate an hour or two before intercourse so that you're able to delay ejaculation during sex.
2. Avoid intercourse for a period of time and focusing on other types of sexual play so that pressure is removed from your sexual encounters
3. Use of a method called the pause-squeeze technique
How to use Pause and Squeeze technique
During masturbation when you are just about to ejaculate, 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.
After the squeeze is released, wait for about 30 seconds, then go back to stimulating yourself for ejaculation again. You may notice that squeezing the penis causes it to become less erect, but when sexual stimulation is resumed, it soon regains full erection.
If you again feel you're about to ejaculate, 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 pause-squeeze technique.
