The Squeeze technique was popularized by Masters and Johnson in the 1970s — it works on a similar principle to stop-start, but uses additional physical pressure to suppress the ejaculatory reflex.
Precise technique: As ejaculation approaches, the partner (or the person) applies firm pressure to the base of the penis, where the head meets the body, with the index finger and thumb for 3-4 seconds.
Why it works physiologically This pressure temporarily reduces blood flow and depresses the nerve bulb that triggers the ejaculatory reflex, thereby temporarily reducing the level of arousal without completely losing the erection.
Proper timing Applying pressure too early can cause you to lose your erection altogether—you need to apply it right when you're getting close to the "point," not earlier.
Comparison with Stop-Start Studies find both techniques to be equally effective—the choice is often a matter of personal comfort.
