Step 1: Identify what the manoeuvre does. The squeeze technique is a learned behavioural exercise from Masters and Johnson sex therapy aimed at giving a man control over the timing of his climax.
Step 2: The method: as orgasm approaches, firm pressure is applied just below the head of the penis until the urge to ejaculate fades, sometimes with a slight loss of erection. Stimulation is then resumed, and over repeated sessions the man learns to postpone ejaculation.
Step 3: Because the whole purpose is to lengthen the time to climax, the condition treated is premature ejaculation. It does not address the inability to get an erection (erectile dysfunction), nor does it alter the direction of seminal flow as in retrograde or antegrade ejaculation.
