So, he is a double of Alex Portnoy,

他是亚历克斯·波特诺伊的分身
with a difference, though;so, instead of masturbation,

区别仅在于他们一个是自慰
it's sex with the needy, essentially,sex with the love starved,

一个与穷人本质上是渴爱者做爱
virgins, older women, widows, etc.

与处女年长妇女寡妇等人做爱
So, the immediate difference that Foer is pointing to,

弗尔指出了他们之间直接的区别
is the difference between something like solipsism or narcissism,

这就是类似唯我主义或自恋的
desire as the fuel for that narcissism,

驱使自恋的欲望
versus desire as the fuel for community and connection.

与推动社会与社会关系的欲望的不同

And it's the trouble that interests me,

而正是问题本身引起了我的兴趣
and that I think he takes from Roth

and that's the impossibility of ever actually making

是贯穿始终的不可能造就了
