我确实是个路盲，一直没找到一个满意的英文对应表达，“方向感不好”自己意淫的说法是：I have a poor sense of direction. 必应搜索这句话，结果有：

My sense of direction is poor to the point of...

Terrible sense of direction? Here is the reason...

13 signs you have a bad sense of direction...

I have a bad sense of direction! Any one eles?

有类似的表达，意淫的还算靠谱。

上下班途中听EnglishPod，听到一个既简洁又地道的说法：

I'm terrible with directions. 根本不需要把“感”sense译出来。

I'm terrible with...几乎是个百搭句，后面随便加：

You're terrible with numbers. You can't remember your own telephone number.

I'm terrible with directions.  I'm always getting lost.

I'm terrible with faces. I can never remember what people look like.

心得：与其冥思苦想去意淫，不如多听多读。听和读的重要性见下图（来自我的老师Albert Wolfe博客）：

没有reception，哪有production。
