Hi/Madam, Welcome to Health Care Magic I can certainly understand your concern and worry ,I would advise you to discuss with your husband regarding mutual sexual fantasies and you can also advise him to check his 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 with his erection .If it is normal , there is nothing to worry it is unlikely that your husband is suffering from any erection problem, he might be stressful with his busy schedule so try to spend some time with him and allow him to discuss his problem with you about his sexual performance . I would advise you to follow a simple method called Master and Johnson technique which would certainly help you couple, .In that the lady partner has to make some signal or she can squeeze ( squeezing technique )the penis forward just before he ejaculates , which would make his erection to last longer and sexual satisfaction would be great... This method is very effective but it takes little time for the couple get appropriate result in it, so be patient and be relaxed. The Other advise I can give you is, if he is anxious and stressed you could ask him to take anti anxiety drugs like escitalopram which would help him to get relief from anxiety and fear.I advise you also not to worry too much about about your relationship, because there might be any other relevant cause that which affecting your sexual performance so please follow these techniques and consultant your Psychiatrist for further help Post your further questions if any, I will available to take up your follow up questions Thank yous
