The key to learning how to delay ejaculation is to train your mind and body to perform as you please. There are many things you can do to learn the art of ejaculation. The most important thing is to simply know and control your body.
But first, you need to know your body. Know what it can do and not do. Leave the signals it gives you and respond to them. We all have different points that draw us to the point "No Return" Know your point, know what it takes to get there and learn not to reach that level so fast.
When you are thinking that you are about to have sex, it is good to do masturbation and before you leave. Wait a few minutes and do it again. Do not let your body go until you are ready to leave. Don't give up on the motive. When you feel the need hard and fast to get them down with a strong hand and grab the base of the penis and squeeze it hard.
Learn the breathing rule. When you are close to dropping the ejaculation, take a deep breath through your nose as deep as you can and hold it for at least five seconds and up to ten. Then slowly pass through your mouth. Repeat this until you are back in control.
Edit Places. There are so many positions you can try. Don't be shy and just go for it. Slow down your blows and breathe. Missionary style is NOT best for controlling your ejaculation.
Something you can try as a technique to train your body before having sex is the cold water treatment. Whenever you take a shower, the last thing you do is adjust your genitals with cold water, cool cold is good. The idea behind this is the penis and the testicles need lower temperatures and therefore they are outside the body. This keeps sperm production at its best.
The goal of doing this, and you can switch while you say a cold and hot shower, cold and hot, just make sure the last one is cold. What this happens is to give your testicles a go. Because the cells and muscles are contracted and enlarged, contract and enlargement repeatedly. Do you not see good work?
