Hi Thank you for asking HCM. I have gone through your query. Your problem can be most likely due to anxiety. You can practice stress relaxation exercises like breathing exercise. Get enough foreplay before intercourse. If you having strong morning erections you are organically fine. If still not helping then a counseling with psychologist should be done. Even after this there is no improvement then SSRI drugs like dapoxetine can be taken prior to intercourse. Hope this my help you. Let me know if anything not clear. Thanks.
