Hi, Thanks for posting in HCM. I understand your concern. Since you have already been examined by Physician and found no abnormality, it appears that your problem is more of psychological. You can try following things, which should work out. Before going for medications, practice pause and squeeze technique . You need to press the base of the penis during erection when you are about to ejaculate and hold it on till the desire goes and your penis becomes flaccid. This can be tried for about 5 to 6 times regularly. You can use a topical lignocaine gel locally, half an hour before sexual activity. It reduces the sensitivity of glans and somewhat delays the ejaculation. If these things are not working well, combine above with Serotonin uptake inhibitors (SSRIs) medications like fluoxetine, which are effective in premature ejaculation. Kindly consult Psychiatrist/Sexologist in this regard for appropriate management. Wish you all the best.
