Hello,
Welcome to the ehealthforum and I am really glad to help you out.
Your concern is regarding the early ejaculation that your husband is having. The symptoms that your husband is having can be due to premature ejaculation. It is most often caused by anxiety and too much stimulation. Depending on when premature ejaculation has started, it can be primary or secondary. The treatment of premature ejaculation is having a psychological session with the couple, using stop-start or squeeze-pause techniques, desensitizing creams and SRRI (selective serotonin reuptake inhibitors) in severe cases. I would suggest that you consult a venereal and sexual health expert and discuss this with him.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are advised to consult your doctor. I sincerely hope that helps. Take care.
