膨脹問題: 缺乏勃起 - 社會心理原因

繼發性缺乏勃起
在發病上占第二位的繼發性缺乏勃起可能也需要這樣的性治療。此型罹病的男子在其一生中的某個時候有能力性交，可是已經幾乎或完全喪失了這種能力。他們也根本不再有勃起，或在大多數的時候未有勃起。當然，我們必須謹記，偶爾的缺乏勃起是完全正常的。畢竟，男人不是一架機器。有的時候，當勞累、悶悶不樂、心煩意亂或醉酒了，他們也許會感到意亂情迷，可是他們的身體簡直不聽使喚。在這種情形下，急急忙忙的投入、主觀意願的驅使或特別的技巧將都不會有什麼結果。我們倒是建議這樣的性伴，要仔細地思量，接納這種局面，盡可能地好好配合。例如，也許要銘記，一名男子並不需要勃起才能滿足他的性伴。用手就能把疲軟的陰莖“塞”入陰道，甚至於此後的陰莖仍然疲軟也無妨，性伴雙方可以轉用性交的某些動作。用這種方式，女方要達到性高潮並不是根本不可能的。此外，男方也可以用手、用唇和用舌來做愛。不管怎樣，男方要放鬆心情，在另一個時候，當健康狀態有所改善的時候，陰莖將會再次很容易地勃起來。

Problems of Tumescence: Lack of Erection - Psychosocial Causes

Secondary problems
Such therapy may also become necessary for a second much larger group of men - those who have been capable of coitus at some time in their lives, but who seem to have lost much or all of this capability. They either no longer have any erections at all, or fail to have them a great deal of the time. It has to be remembered, of course, that an occasional lack of erection is perfectly normal. After all, men are not machines. Sometimes, when they are tired, worried, distracted, or drunk, they may feel amorous, but their bodies simply refuse to respond. In such a case, frantic efforts, will power, or special acrobatics lead nowhere. Instead, the couple is well advised to accept the situation and to make the best of it. For instance, they might remember that a man does not need an erection to satisfy his partner. A limp penis can be "stuffed" into the vagina by hand and even if it then remains limp, the couple can go through some motions of coitus. It is not at all impossible for a woman to reach orgasm in this way. Furthermore, the man can also make love with his hands, lips, and tongue. In any case, he can rest assured that, at another time when conditions are more favorable, the penis will easily become erect again.
