Men with an erection disorder often do want to have sex, but their penis doesn't get stiff enough or doesn't get stiff at all. It can also happen that the penis is stiff at the beginning of making love, but gets soft after a while. When a man has drunk too much or is very tired it is common that these problems occur. It is when the complaints are regular or are always present that one can talk about a disorder. An erection problem may reduce the desire to make love and the fun in making love. Men often fear that it will happen again next time. The partner may also have problems with it, like being afraid of not being attractive anymore or being disappointed.
