A very simple way to delay this is the squeeze technique
. The compression technique is to put an end to the stimulation just before orgasm. You or your partner places a thumb on the brake (the skin connecting the tip and right under the head of the penis) and applies pressure to the head of the penis with the other fingers. Maintain pressure until the urge to ejaculate subsidies. Then you can continue to have sex and repeat the process until you actually want to ejaculate.
