Thanks for asking. I can understand your concern. There are many causes for poor erections, lifestyle associated factors, improper masturbation habits, problematic pornography use, lack of correct knowledge and misconception regarding sexual facts, etc these all can cause sexual problems. A detailed history and information regarding these areas is required to consider before diagnosis of Erectile dysfunction and its treatment. As one should look after his or her health, sexual health is also a matter to be given importance. A proper understanding about intercourse, realistic expectations, sexual hygiene, differences in male and female sexual responses, etc is needed if one wishes to enjoy sex life in a true sense.
