膨脹問題: 缺乏勃起 - 社會心理原因

原發性缺乏勃起
有一些生理上健康的男子，當他們嘗試著性交的時候，一生中從未有過勃起。更確切地說，在面對一個性伴的時候，他們的性反應完全地被抑制了。這種症狀可能有多種病因。不過，各種不利環境條件的綜合作用是通常的病因。
例如，一個男性可能由一個有佔有欲和非常有魅力的母親養大，這個母親恰恰不允許他“不受自己控制”，或者他被灌輸了錯誤的觀念，對性行為抱有罪孽感、骯髒感、“過於費解”或危險感。假如這個男子第一次嘗試性交時失敗了，他也許始終不能克服自己的這種消極心理條件作用(negative conditioning)。在另外的例子，一個男性也許有著濃厚的同性戀傾向，而且恐懼自己成為同性戀者。這種悠忽不定的內心衝突然後來會抑制其生理功能的完全發揮。顯而易見，在這些和類似的病例中，他們更多地需要來自於外部的幫助而不是僅僅依靠來自于他們的女朋友或妻子的幫助。真真切切地說，他們的最大希望在於強化的性治療。

Problems of Tumescence: Lack of Erection - Psychosocial Causes

Primary problems
There are some physically healthy men who never in their lives had an erection of the penis when they attempted coitus. That is to say, in the presence of a partner their sexual response is completely inhibited. This condition can have several possible causes. Usually, however, it is brought about by a combination of unfortunate circumstances.
For example, a male may b raised by a possessive and highly seductive mother who just does not allow him to "be her own man", or he may learn to think of  sexual intercourse as sinful, dirty, "too complicated", or dangerous. If such a male then fails the first time he tries coitus, he may forever remain unable to overcome his negative conditioning. Another male may have strong homosexual tendencies, but may fear to come to terms with them. The unresolved inner conflict may then prevent his body from functioning properly. Obviously in these and similar cases, a man needs more help than he is likely to get from his girl friend or wife alone. Indeed, his best hope is intensive sex therapy.
