Hi Sir,
Welcome to Health Care Magic
I can certainly understand your concern
There is nothing to get panic in your case, as withstanding of erection during sex mainly depends on sexual stimulation and blood flow to the penis....I would like to know whether you are on any medications...like propanolol which may cause
erectile dysfunction.
I would suggest you to promote good sexual stimulation , get relaxed urself during sex, avoid alcohol and
smoking if any, maintain healthy life style and adequate weight, and you can try with
pelvic floor exercises which can help you better.Finally ,if you could not find any improvement with these measures, you can take drugs like
sildenafil which helps you better to withstand erection...Which depends on the production of nitric oxide (NO). You can consult a good
psychiatrist to get some counseling and other therapeutical measures
Post your further questions if any, I will available to take up your follow up questions
Thank you
