Dear service user, Thank you for writing to Healthcaremagic. I got your question and understand your concern about erectile dysfunction in your partner. If your husband can achieve and maintain good quality of erection during masturbation (as you said) but looses soon before vaginal containment. This happens to newly married couples when one engages in sexual intercourse. It is likely to be performance anxiety. I recommend to consult a psychiatrist for this. There are effective behavior therapies and counseling techniques which can prove useful to both of you. This will help him to come out of anxiety. Warm regards and wish you good health.
