Have you guys learn anything from tantric love making skill? It's kinda strange when I read it online, but I do get some basic things that can help to perform longer love making. The 3 main point that can help you to perform better is PC Muscle contraction, penis squeeze, change of sex position and breath technique.
PC Muscle (pubococcygeus muscle) is the muscle between your pubic bone and tail bone. You can feel this muscle when you are urinating, try to stop the flow, the muscle that controls it is the pc muscle. Read a few of the articles before, this muscle can help you to enhance your sexual performance by stop ejaculation. How do you train your pc muscle? Contract this muscle 20-25 times a day.
Penis squeeze tip, this is an easy and able to use it without much training. When you are near to orgasm, you can delay your ejaculation by pulling your tested down and away from your body. This training can ultimately help you to reach pleasure without ejaculation.
Change of sex position able to prolong the love making process, this I know. When you change your sex position, you may feel not the urge to ejaculate immediately, thus this definitely helps to delay ejaculation. You may try position that you are lying down on your back and she is on top of you facing or the other way, as long she is on top she will be the one to control the rhythms. This will help you to delay ejaculation as you won't feel the urge to ejaculate so strong. Search online for Kamasutra and try some new positions that both of you enjoy it, then you may find some positions that can give her the pleasure but help you to stand longer time.
Breathing techniques, when you are having sex, the breath tend to be quick. When you are close to climax, you may tend to hold your breath as well. Practice your breath to be steady, relaxed, deeply and slowly, this is effective to stave off your orgasm. This same breathing technique is useful for running too as I read in other article.
