Hi there, Welcome to HealthcareMagic, I have gone through your query in detail and can certainly understand your concern and worry. I would advise you to check your sustainability of erection by a simple test called NPT penile tumescence in which erections occur in the early morning during sleep which can rule out any problem If it is normal, there is nothing to worry it is unlikely that you are suffering from any erection problem. So, I can say that you might be stressful with your busy schedule to try to spend some time with your partner to get rid of any understanding problems or anxiety. I would advise you to follow a simple method called Master and Johnson technique which would certainly help you. In that, the lady partner has to make some signal or she can squeeze (squeezing technique) the penis forward just before you ejaculates, which would make your erection to last longer and sexual satisfaction would be better. This method is very effective but it takes little time for the couple to get appropriate result in it, so be patient and be relaxed. The other advise I can suggest is, if you are anxious and stressed you may need to take anti-anxiety drugs like Escitalopram (prescription based medication) which would help to get relief from anxiety and fear. Still is it is not better, you can take sildenafil tablets. So please follow these techniques and consultant your Psychiatrist for further guidance. Please post your further questions if any. I will available to answer your follow up questions Regards Dr. Soujanya
