"Death grip syndrome" is a forum word, not a diagnosis
The thing underneath it is real. The syndrome, with a name and a cure, is not.
There is no entry for death grip syndrome in any diagnostic manual, and no controlled study has ever measured it. The phrase appeared on forums and spread because it names something men recognise, which is a good reason for a word to spread and no reason at all to treat it as established.
What is documented is narrower and duller. A narrow, high-pressure masturbation habit is common among men who have trouble finishing with a partner, and varying the habit helps. That describes a learned pattern, not damage, and nothing in it suggests a nerve has been worn out.
What to do with it
If the pattern sounds like yours, the useful response is not a diagnosis but a month of deliberate variation: grip, pace, position, pressure, and how often.
If nothing changes after that, it belongs with a doctor or a sex therapist rather than with a forum. Delayed ejaculation has other causes, including several common medications, and those are not fixed by changing your grip.
More numbers of the same kind, with their sources, are under the myths on sex-facts.com.
