再来纠正一下FLYINGUFO的说法, MASTERBATION这个词的来源:
"The word masturbation is believed by many to derive from the Greek word mezea (μεζεα, "penises") and the Latin turbare ("to disturb"). A competing etymology based on the Latin manu stuprare ("to defile with the hand") is said by the Oxford English Dictionary to be an "old conjecture". The esoteric and little-used synonym manustupration is similarly derived from manus stuprare."
"It is held in many mental health circles that masturbation can relieve depression and lead to a higher sense of self-worth (Hurlbert & Whittaker, 1991). Masturbation can also be particularly useful in relationships where one partner wants more sex than the other ― in which case masturbation provides a balancing effect and thus a more harmonious relationship."
当然, 你所说的是Compulsive masturbation, 那是sexual addiction syndrome的一种, 也就是说是一个对性上瘾的一种. 换句话说, 也就是如果有伴侣的话, 就算不手淫也会产生上瘾的.
