If a man is not able to achieve or maintain an erection strong enough for a sexual intercourse it is the defining symptom of a possible erectile dysfunction. The problem may have different “levels”.
If the dysfunction:
- Happens only occasionally, the problem should not be serious; all men may face problems with erections at some time within their lives.
- Proceeds continuously and grow up gradually, the cause may have a physical basis; this is generally the situation of a chronic impotence.
- Happens abruptly and you still experience early-morning erections and are capable to get an erection with masturbating, the reason is likely to be a psychological one, perhaps there is also an underlying physical cause.
